Religious conversion is the aoption of a new religious identity, or a change from one religious identity to another. This typically entails the sincere avowal of a new belief system, but may also present itself in other ways, such as adoption into an identity group or spiritual lineage. "Conversion" occurs not only from one religion to another, but also between different sects, such as Protestant denominations, within the same faith, when this involves a felt change of identity rather than other reasons such as convenience.
