In the Nicene Creed, why do we confess one baptism?
to confess:
to acknowledge belief or faith in
to declare as true
To me, confessing something implies having done something wrong. However, having been baptized isn’t something wrong, is it?
It does not mean that kind of confess.
Confess has more than one meaning.
Is being baptized more than once wrong?
Well, firstly, it is not possible to be baptized more than once.
What this is referring to, however, is the early Church heresy regarding baptism in schismatic or heretical groups, or the “re-baptism” of those who defected or denied the faith and then returned.
The Church delcared that there is only ONE baptism for the remission of sins. It cannot be repeated, and schismatics and heretics can validly baptize. Therefore, no one who has been validly baptized is “re” baptized when they are received into the Church.
That is why we do not baptize those who have already been baptized in Protestant denominations.
This was such a serious controversy in the early Church, that the Fathers believed it necessary to add this to the Creed to ensure right belief on this topic.
Therefore, we declare (confess) this teaching when we say the Creed.
