Would Nicene Christians consider a Unitarian Baptism sufficient for entry into the Church? 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?
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.
