Definition:
The word "unbaptized" is an adjective that describes someone who has not undergone the Christian ritual of baptism. Baptism is a ceremony where a person is welcomed into the Christian faith, usually involving water.
In more advanced discussions, "unbaptized" can be used metaphorically to describe someone who has not been introduced to a particular experience or set of beliefs. For instance, "He approached the world of art like an unbaptized soul, curious and uninitiated."
While "unbaptized" primarily refers to a lack of baptism in a religious context, it can also imply a lack of initiation in non-religious contexts. For example, someone might feel unbaptized in a new job if they haven't been properly trained or welcomed into the company culture.
There are no specific idioms or phrasal verbs directly related to "unbaptized," but you might use phrases like "not yet initiated" or "new to the experience" in similar contexts.
In summary, "unbaptized" refers to someone who has not received the Christian sacrament of baptism.
