The study of salvation or, more specifically, the doctrine of salvation from our sins.
Etymology: (from etymonline)
“1847, in reference to health; 1864 in reference to salvation, from German soteriologie, from Greek soteria “preservation, salvation,” from soizein “save, preserve,” related to sos “safe, healthy,” of uncertain origin (perhaps from PIE root *teue- “to swell”). With -ology.”
Studying salvation helps us to understand our faith more deeply as well as enables us to give account of it to those outside the faith (aka witnessing).
Key questions discussed in this area of study today include:
Is baptism required for salvation?
What does it mean to be a born again Christian?
Once saved are you then always saved? (Can you lose your salvation?)
It ultimately helps us understand other related doctrines such as redemption, sanctification, justification, propitiation, and substitutionary atonement. Many of these doctrines will appear in later posts.
This should at least give you an idea of what this area of study covers as well as provide you some material to begin digging into the doctrines of salvation.
Until next time!
Oh! And HAPPY NEW YEAR!!
