According to Catholic thought, if we are washed of Original Sin at the time of baptism, why do we transmit Original Sin to our children? In other words, how is it that my child is born with Original Sin when I was freed from Original Sin at the time of my baptism?
I think you misunderstood the role of Baptism in Catholicism.
Cathecism of the Catholic Church-1263 says
It doesn't say original sin is washed away, it says it is forgiven. Forgiven doesn't mean you don't have original sin anymore; it only means your sins are forgiven.
Our sins cannot be washed away by merely washing with water nor any kind of Baptism. Only the blood of Jesus Christ can wash away our sins.
Original sin is a state of human nature passed to all mankind, but it is not like a gene passed on from our immediate parents. It affects the nature of all humans. The Catholic Catechism discusses this in and around paragraphs 396 to 408.
In paragraph 404 talks a bit about what Original Sin is and its source:
In paragraph 405 talks about what Original Sin is and the effects of Baptism on it:
On the effects of Baptism, paragraph 978 says:
Finally, in talking about Baptism of Infants in paragraph 1250:
Not being a Roman Catholic, I cannot give you an answer from the RC perspective and tradition. I can, however, give you a brief overview about what the Bible has to say about Christian baptism.
As a wise man once told me,
As good as infant baptism may be as a way for Christian parents to "sanctify" their offspring through a well-established rite (which exists in both the Catholic and Protestant traditions), nowhere in the New Testament is there any indication that infant baptism cleanses the infant from "original sin." If the RC church teaches this, all I can say is, the teaching is not biblical.
On the basis of Scripture, I say confidently but lovingly, the physical act of being baptized neither forgives us of sin nor frees us from sin. To say otherwise is to contradict the clear teaching of Scripture. If, however, Scripture is not the ultimate guide for your life and practice, then none of the following will be of help to you, and will certainly not answer your question--though I am glad you asked it!
There are two baptisms in the New Testament, each having two aspects, both spiritual and literal/physical. The first is the baptism of John.
John the Baptizer fulfilled two roles: the first as a herald for the Messiah, and the second as a forerunner for the Messiah.
John, however, shouted
John certainly attracted the attention of the people with his announcement of the coming kingdom, and they came to him in great numbers.
What was hindering the entrance of Jesus the Messiah into the hearts of the people? Sin. John therefore had to tell the people
Just as the forerunners of old were responsible to remove obstacles from the road, so too was John responsible to get people to repent of their sins, removing anything that would hinder the entrance of Messiah into their hearts and lives.
John's message to the crowds who came to hear him was a simple one:
And repent the crowds did! Repentance is simply a change of mind resulting in changed behavior. It's doing an "about face": you are going in one direction, but you make a 180-degree turn and go in the opposite direction.
Before a watching world, the people baptized by John were declaring openly in the waters of the Jordan River--that's the literal/physical part of baptism--what had transpired inside their hearts--that's the spiritual part of baptism; namely, that they were turning their backs on their sins in preparation for the appearance of the coming Messiah, whose coming John foretold.
Being baptized did not cleanse anyone of sin, it merely bore witness to their repentance. On the other hand, the baptism of the Messiah was completely different. As John himself said of Jesus, the coming Messiah and king:
The second baptism, then, is Christian baptism. Like John's baptism, it has both a literal/physical aspect and a spiritual aspect.
The physical aspect is the outward act of being immersed in (or sprinkled by) actual water in the presence of witnesses, and
The spiritual aspect is the inward process of conversion by the Holy Spirit, which takes place before we are baptized. Call it regeneration, as in
or call it being born again or born from above, as in Jesus' words,
Christian baptism is for believers in Jesus Christ who have been regenerated within their spirits by the Spirit of Christ, whom Jesus called a "Helper," "the Spirit of truth" who "teaches us all things," and the presence of Christ within us "forever" (see John 14:16 and ff.). Believers who are indwelt by the Holy Spirit want to bear witness to that transformation by obeying the command of our Lord to be baptized. To this day, in some countries of the world, being baptized openly and publicly is to invite persecution and even death!
As Paul tells us in Romans 6, Christian baptism is a symbol of our having died to our old way of life. When we die, we need to be buried. Baptism, then, is a picture of burial that is enacted symbolically by immersing ("burying") a person in water. As the person comes up out of the water, symbolically he is coming alive in the Spirit of God, just as Jesus came alive in His glorious resurrection from the dead (vv.3-5 and ff.).
Does being baptized mean we will never sin again? No. Neither an infant who has been baptized nor a person who has experienced the new birth and has been baptized will cease to sin (see 1 John 1:8-10). We can, however, have victory over sin in our lives, since as believers in Jesus
Furthermore, we have the responsibility as baptized believers (literally and spiritually) to
In conclusion, being baptized with water neither cleanses us from sin nor takes away our ability to sin. It is, however, a way of telling both God and man that we have become new creatures in Christ, that
