What determines entry into Christendom - baptism or belief? Say a vaguely spiritual person joins a congregation affiliated with the Unitarian Universalist Association of Congregations. Sometimes, the congregation may pull readings from the Hebrew scriptures or the Christian scriptures, and over time, the vaguely spiritual person decides to identify himself/herself as Christian by belief, and therefore repents and does other Christian things. Now, the UUA does not normally perform baptisms as a ritual. Would such a person be considered a legitimate Christian? Would the UUA be willing to perform a baptism for the Christian convert before the congregation, since baptisms are very significant in Christianity?

  • From the help pages "Who are considered Christians here? As far as the scope of this site is concerned, any group that identifies themselves as Christian are to be considered on-topic and allowed to label themselves Christian. " While this is a good question in general,it might not be a good fit for this particular site. If left to stand, it must be addressed carefully to avoid being a violation of the site guidelines.

  • I think we need to understand what is meant here by the term Nicene Christian. Also what is meant by the Church. Some churches do not accept baptisms by others to be sufficient for entry into their congregations.

  • If you chose to be baptised in a Unitarian Church and you accept Christ you are a Christian...if not it is a naming ceremony. Unitarians have choices and personal beliefs can be extensive. MLHKaye

  • I think "Nicene Christian" is too broad a group for this question. Different denominations may have different answers. Aug 11, 2013 at 6:45

For many Baptists, the answer is fairly simple and is well conveyed by the saying "Baptism is merely an outward manifestation of an inward decision." For those on that end of the baptismal spectrum (where it is a sign rather than a sacrament), the question is thus fairly moot.

The difficulty in assessing the "validity" of a baptism comes from those who view baptism more as a sacrament - an act effacious in and of itself. For such a situation, the nature of the Baptism coming from such a far out denomination as the Unitarians would probably lead to some consternation. Unitarians differ widely from mainstream, Nicene Christianity, in their rejection of the Trinity and the exclusivity of Jesus as "the Way, the Truth, and the Life." What was conveyed in a UUA baptism would doubtless be of concern to any priest considering the validity of that baptism.

As to whether or not baptism is required for entry into heaven, however, even the most sacramental - the Roman Catholic church, explicitly recognizes the "Baptism of Desire," meaning that if a person truly intended to be baptised but died before the actual dipping occurred, they are still "baptised" enough for entry into the Kingdom. Thus, the answer for most Nicene Christians would be "Belief is enough, but you still should get baptised if you can."

In any event, most churches are happy to baptise anyone who has made a decision for Christ.

  • +1 But "baptismal spectrum"? Perhaps "baptismal belief space" might be more accurate? :-) Presbyterians generally teach it is a "sign and seal", but they do not restrict it to confessors nor do they believe it regenerates. Hmm. I wonder if there are questions about re-baptism. ISTR, Catholics have "conditional baptism" to avoid re-baptism. Jun 18, 2013 at 15:31

    "In any event, most churches are happy to baptise anyone who has made a decision for Christ." I don't think this is true. If the person has previously been baptized, most denominations that consider it a sacrament will resist rebaptizing them after a "decision for Christ". The rules may vary by denomination if the first baptism was done by a UUA. Aug 11, 2013 at 6:50

Μετανοεῖτε καὶ πιστεύετε ἐν τῷ εὐαγγελίῳ.

Repent and believe in the Gospel.

Mark 1:15.

Of course, this cannot be accomplished unless the Father draws a man to His Son, as it is written (John 6:44),

No one can come to me unless the Father who sent me draws him, and I will raise him on the last day.

    +1 The "repent" is critically important to properly understand what "believe" means. Biblical belief is not a mental ascent to the facts of who Jesus is and what He did on Calvary for even Satan himself understands this (James 2:19). No, biblical belief involves denying one's self and submitting to Christ's authority (Luke 9:23). Stated another way, it centers around the idea of Jesus as Lord (Acts 16:31, Romans 10:9,13). Baptism follows that.

  • The question is specifically asking whether Trinitarian churches and denominations would accept a Unitarian baptism as "valid"—that is, was it a "real" baptism, or must they be baptized ("again") to receive church membership. The question is not about requirements for salvation. Aug 11, 2013 at 3:30

    Wow, that is quite a different question. I'm disappointed (not with you, of course) that questions can be changed after answers are written, like pulling the rug out from under my feet. Aug 11, 2013 at 4:24

As user Ignatius Theophorus stated, Catholics do accept baptisms performed in other denominations as valid. The catch is that the baptism must also be performed properly to be valid.

Baptism not done "in the name of the Father, and of the Son, and of the Holy Spirit" would not be considered a true (valid) baptism. The problem is not that it was performed outside the visible Catholic Church. The problem is that it was not performed in a valid manner.

The same applies to the Orthodox Churches generally, although there may be parishes that apply stricter guidelines for baptism. The more traditional Protestant churches (such as Lutheran and Anglican congregations) tend to be similar to Catholic practice.

Evangelical denominations may vary in practice, although practice tends to be based on a belief in baptism as an outward sign and not as a sacrament. Some evangelical churches may recommend a full baptism as a "public declaration of belief"; if the Unitarian baptism was not an intentional of repentance and faith, it would probably not be "accepted". People entering such congregations might also choose to be re-baptized if they had been baptized as infants, even in a Trinitarian church, but do not identify with that baptism as part of their personal Christian path. On the other hand, still reflecting the non-sacramental view of the rite, other evangelical churches may not view baptism or the validity thereof as a major issue, leaving it to the will or conscience of the person in question.


The Catholic Church provides a clear answer: those who are baptized are members of the Church, period. There are those who die outside the Church who we believe are still redeemed, but it is only in that redemption that they enter into the Church. Yet even these are still said to have a sort of baptism.

Since this answer has gotten a few down votes, I'll add some clarity.

Baptism makes us members of the church:

Through Baptism we are freed from sin and reborn as sons of God; we become members of Christ, are incorporated into the Church and made sharers in her mission: "Baptism is the sacrament of regeneration through water in the word." (CCC 1213)

Anyone can baptize:

The ordinary ministers of Baptism are the bishop and priest and, in the Latin Church, also the deacon.57 In case of necessity, anyone, even a non-baptized person, with the required intention, can baptize58 , by using the Trinitarian baptismal formula. The intention required is to will to do what the Church does when she baptizes. The Church finds the reason for this possibility in the universal saving will of God and the necessity of Baptism for salvation.59 (CCC 1256)

I haven't found anywhere in the CCC which is quite as succinct in describing the actual rite requirements, but this site's description is accurate.

the essentials of that rite are two: the pouring of water over the head of the person to be baptized (or the immersion of the person in water); and the words "I baptize you in the name of the Father, and of the Son, and of the Holy Spirit."

Of course, missing from that paragraph is the fact that the intent of the person baptizing is required.

The internal intention (intentio interna) of the minister of the Sacrament must be, as defined by the dogmatic Council of Trent "doing what the Church does." The minister of a Sacrament may be a schismatic or an excommunicate, and the Sacrament is still valid, as long as this intention is present. An example would be the case of an atheist in an emergency baptizing a newborn infant. Even though the atheist personally does not believe in the Sacrament, as long as he intends to do what the Church does in this instance, perhaps out of his concern for the infant, the Sacrament is valid.

And so we arrive at the original point. So long as you baptize with water and intend to baptize in the name of the Father, the Son, and the Holy Spirit, you are committing a valid baptism. And the person baptized will be a member of the Church.

    I'm frankly skeptical that this is the full Catholic answer, that any baptism under any creed is efficacious.

    Yes, baptism as understood by the Orthodox Churches (RC, Anglican, Eastern Orthodox etc.,) has to be performed in a specific manner with specific understandings of the meaning of the act and the meaning of the words spoken during baptism. The Anglican and Catholic Church do not accept Mormon baptisms even though they are done in the name of the Trinity in Unity, because the Mormon understanding of the Trinity is "unorthodox."

    According to Catholic teaching, a non-Catholic can validly baptize, but must have at least the intention of "doing what the Church does." In addition there are requirements about the form of the sacrament (the words prescribed by Christ) and the matter (water), but even apart from these additional requirements, I doubt that a unitarian would have the necessary intention except in very unusual circumstances. If someone baptized by a unitarian became Catholic, he would surely be baptized - conditionally if there is some chance the unitarian baptism is valid, but probably unconditionally.

  • @AndreasBlass As an interesting follow up point: a number of years ago, the Church decided that Mormon baptisms are also insufficient and that all members of the Church of Mormon, who had not been baptized otherwise, will be baptized unconditionally. Aug 8, 2013 at 2:32
