The word priest comes from the greek word presbuteros. That word was transliterated into Latin as presbyter, which then in English became shortened further to 'priest'.
Though many might translate this word only to mean ‘elder’ we see in scripture that it is very often tied to the context of priestly functions. Thus certain translations of passages, like the douay rheims version, render passages like Titus 1:5, and James 5:14-15 to actually say 'priest' when referring to presbuteros. In this Bible Study we will look at the Biblical basis for the Royal priesthood of all the baptized, the High Priesthood of Christ and the Catholic ministerial priesthood.
