Are there any Christians who are scientists who believe in modern miracles?
Yes! One of them currently serves as the President of my church.
Russell M. Nelson - renowned cardio-thoracic researcher & surgeon, and currently serves as President of The Church of Jesus Christ of Latter-day Saints. I'll share several statements he made in a sermon in 2018 regarding the involvement and intervention of God in our lives:
If we are to have any hope of sifting through the myriad of voices and
the philosophies of men that attack truth, we must learn to receive
Our Savior and Redeemer, Jesus Christ, will perform some of His
mightiest works between now and when He comes again. We will see
miraculous indications that God the Father and His Son, Jesus Christ,
preside over this Church in majesty and glory.
But in coming days, it will not be possible to survive spiritually
without the guiding, directing, comforting, and constant influence of
the Holy Ghost. (source)
Richard G. Scott - nuclear engineer who served as an apostle of The Church of Jesus Christ of Latter-day Saints until his death in 2015.
In his sermon Truth: the Foundation of Correct Decisions he reviewed the roles of scientific & spiritual inquiry. A few of his statements:
There are two ways to find truth—both useful, provided we follow the
laws upon which they are predicated...
- [first] the scientific method. It can require analysis of data to confirm a theory or, alternatively, establish a valid principle
- [second] go to the origin of all truth and ask or respond to inspiration. For success, two ingredients are essential: first,
unwavering faith in the source of all truth; second, a willingness to
keep God’s commandments to keep open spiritual communication with Him.
We can see the scientific method has brought about an extraordinary
expansion of our understanding as the Lord has inspired gifted men who
may not understand who created these things nor for what purpose.
The process of identifying truth sometimes necessitates enormous
effort coupled with profound faith in our Father and His glorified
Son. God intended that it be so to forge your character. Worthy
character will strengthen your capacity to respond obediently to the
direction of the Spirit as you make vital decisions. Righteous
character is what you are becoming. It is more important than what you
own, what you have learned, or what goals you have accomplished.
In all humility, I solemnly bear witness that this creative Master of
unparalleled capacities is our compassionate, holy Father.
Among other things, Elder Scott declares his belief in God's miracles through the creation, redemption, and ongoing revelation. He affirms God's love and power.
Stephen Meyer - geologist & Evangelical Christian, author of Signature in the Cell, Darwin's Doubt, and The Return of the God Hypothesis (source).
Dale G. Renlund - cardiologist & apostle of The Church of Jesus Christ of Latter-day Saints (source).
Many other examples could be cited. Some of them are accomplished but not particularly famous. I personally know multiple scientists who have worked for/with NASA, computer scientists at the leading edge of the self-driving car industry, a physicist in atomic research, etc. who believe in God and in the ongoing reality of His miraculous intervention in human lives.
GratefulDisciple has already offered an excellent review of naturalism--a philosophical assumption--and the role it plays in much of contemporary scientific dialogue. And as already noted by GratefulDisciple, those who religiously adhere to naturalism must exclude the supernatural/miraculous a priori. They rule out a set of possible explanations before even looking at the evidence. This is not very scientific.
I wrote another post on this site discussing verificationism, and why it is irrational to adopt a premise such as "you shouldn't believe anything that can't be demonstrated by science". No scientifically-minded individual can adopt that maxim consistently.
These samples look like the population we sampled them from!
It is sometimes asserted that "most contemporary scientists are atheists or agnostics"...though to be scientific about it we have to at least acknowledge the possibility of a titanic lurking variable: if theistic beliefs threaten one's job security, theistic beliefs are more likely to be kept quiet on the job.
That said, it is worth pointing out that many at the forefront of the modern scientific revolution were devout theists--including individuals such as Boyle, Kepler, Galileo, and Newton--who sought to discover the laws of the universe because the Deity they believed in was a Being of order who governed the universe by law.
At a minimum, this demonstrates that, at a time when it was publicly acceptable to openly believe in God, many scientists openly believed in God; and, at a time when it is increasingly publicly unacceptable to openly believe in God, many scientists do not openly believe in God.
In other words, scientists look like the culture they come from...this is neither revolutionary nor surprising. It is merely the fallacy of historical presentism to claim that today's culture is in all ways superior to yesterday's culture. The scientists of a century from now will probably hold views common to the culture 100 years from now--which (oh the horror!) will probably be different from that of today.
Are you sure?
Consider running some of your beliefs through this infinite loop:
Select a belief:
a. Do I hold this belief because it was taught to me by somebody else?
b. Do I hold this belief because I tested it?
c. Do I hold this belief because I derived it from first principles?
d. Do I hold this belief because I have ruled out all other possibilities?
Let's try one for example: heavier objects do not fall faster than lighter objects. I first believed this because of case a; people taught me this (and they said there was experimental data to back it up). Then I tested it (case b). I've tested it many times, and I have experimental data to back up what I was taught. This doesn't prove the other people's experiments were valid, but it gives me greater reason to consider the possibility that they were.
Then I did case c; I studied physics and learned (at least at a basic level) why this is true (F = ma & W = mg & F = G ⋅ (m1 ⋅ m2)/(r2). Lamentably, I am not omniscient and I haven't been able to do case d.
At each stage in the process I believed the principle, for a series of developing reasons. If we are truly honest with ourselves, most of our beliefs will fall under case a: even our beliefs based in science.
What about miracles? Most belief (or disbelief) in miracles will fall into case a. But let's say we have personal, observational evidence of miracles...something akin to case b. Now, when we hear report of a miracle, the same concept discussed above about weights applies: this doesn't prove the other people's experiments/miracles were valid, but it gives me greater reason to consider the possibility that they were.
And even if I don't know whether X person's claim of the miraculous is true or not (and I usually won't), because I have experiential & experimental grounds for accepting the existence of the miraculous/supernatural, "miracle" is now in the set of valid explanations to be considered.
For a more detailed discussion of certainty, degrees of certainty, and the relevance of case d above, see the epistemology section of my post here.
Suspending the laws of the universe
Finally, sometimes miracles are described as a suspension of the laws of the universe. While there are some theists who hold this view, there are certainly theists who do not. This is an intra-theism debate, not an atheist vs. theist debate.
If God knows everything; He knows the laws of the universe--including the ones we haven't yet elucidated. It would be entirely possible for Him to use that knowledge of the universe to do something that--by modern understanding--is entirely explicable, and yet follows the laws of the universe without interruption.
This is easily demonstrated. The average human of the 21st century is neither befuddled nor awestruck by a smartphone, and could figure out how it works if they really wanted to. The average human of the 17th century would have been overwhelmed (and probably terrified, started a witchcraft trial, etc.) at the sight of a smartphone, and probably did not have the resources to figure out how it works even if they really wanted to. This is not because humans today are smarter (we aren't), but because we have access to a larger pool of accumulated knowledge (we didn't earn it, we inherited it). We can do things today that are fully in keeping with the laws of the universe, that would have appeared supernatural to people just a few centuries ago.
If flawed, imperfect humans can come that far in 4 centuries, is it not reasonable to conclude that the Omniscient God of the universe could use the laws of the universe to do things we do not understand?
Rather than debate whether God is subject to the laws of the universe or the laws of the universe are subject to God, I suggest a cleaner explanation, the one held by the leaders of the scientific revolution: the laws of the universe describe how God does things.
How can a scientist reconcile the belief in modern miracles with the skepticism of the scientific method?
The scientific method is a brilliant tool for minimizing type-2 errors; skepticism is a philosophy that is sometimes common among practitioners of science, but is not necessary to do science. One need not be skeptical in order to be inquisitive or thorough. In fact, (inductive argument) I have never met a self-professed skeptic who was able to maintain their skepticism consistently--we all believe something.
There is a difference between being convinced that a miracle is possible & being convinced that X incident was a miracle. I believe miracles happen. I also have heard many claims of miracles, and in most cases, I do not know if the claims are true or false.
A scientifically-grounded means of evaluating a miracle would be to consider possible causes (including but not limited to miracles), and look for things that are testable or repeatable. If one is not pre-committed to either a) all claims of the miraculous are false or b) all claims of the miraculous are true (both of which are quite unscientific beliefs), sometimes the evidence will point to a miracle as the most-likely cause, and sometimes it will point to another likely cause.
Can science confirm a miracle?
Science does not prove things (like math or logic can, using axioms). Science disproves things. The current scientific consensus consists of hypotheses that have been extensively tested and nobody has been able to disprove them. Information that is as-yet-undiscovered always holds the possibility of overturning present-day consensus.
At best, then, scientific inquiry could show that state A (pre-miracle) & state B (post-miracle) are different, and that our present knowledge of natural laws does not explain how we got from A to B. The more I study both science and theology the more I am persuaded of the truth of this statement:
Perfect science and perfect theology agree perfectly. It is our imperfect understanding of both that creates the illusion of conflict.
