Soteriology
From Conservapedia
Soteriology, from the Greek σωτηρία sōtēria "salvation", from σωτήρ sōtēr "savior, preserver" and λόγος logos "study" or "word", is the study of religious doctrines of salvation. Salvation theory occupies a place of special significance in many religions. In the academic field of religious studies, soteriology is understood by scholars as representing a key theme in a number of different religions and is often studied in a comparative context, by comparing various ideas about what salvation is and how it is obtained.
