Describing someone or something that has not undergone the religious ceremony of baptism.
The unbaptized children were not allowed to participate in the church service.
Unbaptized → It is formed from "un-" (meaning not) and "baptizare" (meaning to baptize, from Greek "baptizein"). The word "unbaptized" means not having been baptized, or lacking the sacrament of baptism.
Think of 'not' ('un-') having been 'baptized' — that's why unbaptized means someone who has not received baptism.
