What must I do to be saved?
...it seems that I only must believe in Christ and be Baptized???? I did not see anything referring to the Catholic Church..am I missing something?
Acts 26:20 "... [Paul] declared ... they should repent (metanoeō) and turn to (epistrephō) God and perform deeds (ergon) worthy (axios) of their repentance (metanoeō)."
So, "belief" connotes many things, including performing worthy deeds or meritorious (axios) works (ergon).
Moreoever, in Sacred Scripture, the opposite of "believe" (Gk pisteuo) is "disobey."
Kittel's Theological Dictionary of New Testament (TDNT) says "pisteuo means 'to trust' (also 'to obey') . . ." This is confirmed further by John the Baptist's statement in John 3:36 "Whoever believes in the Son has eternal life; whoever disobeys (apeitheo) the Son will not see life, but must endure God's wrath."
So, what is our obligation of obedience, given that "to obey" is implied in "to believe?" Doesn't God give us such obligations? Can we honestly say we "believe" if don't obey? For instance, are we not commanded to obey our parents as our duty in the Lord? (cf. Col 3:20; Eph 6:1). Are we not also commanded to "obey your leaders (hēgeomai) and submit to them" (Heb 13:17)?
Scripture calls the NT Church the "church throughout all (Gk ekklesia kata holos)" (Acts 9:31) from which the term "Catholic Church" derives. Aren't we obliged to obey the "elders" (presbyteros) of this Catholic (kata holos) Church (ekklesia)?
Scripture describes the presbyters, as being ordained (Gk kathistēmi) (Titus 1:5). This Greek word, kathistēmi, means also "make to rule over" (cf. Matt 24:47, Matt 25:21, Luke 12:41, Luke 12:44). Consequently, Scripture tells us to treat our presbyter "as a father (Gk pater)" (1 Tim 5:1). So, given the command within Heb 13:17, are we not called to obey our presbyters? Isn't this also part of the "obedience of faith" (Rom 1:5, 16:26)?
After all, Jesus himself said "He who hears you hears me, and he who rejects you rejects me, and he who rejects me rejects him who sent me." (Luke 10:16)
