Acts 4:12 → Joel 2:32

Peter's climactic declaration — "Salvation exists in no one else, for there is no other name (ὄνομα, onoma) under heaven given to men by which we must be saved" (Acts 4:12) — draws its "name … saved" logic straight from Joel 2:32: "everyone who calls on the name of the LORD (בְּשֵׁם יְהוָה, beshem YHWH) shall be saved." Peter had already quoted Joel 2:32 explicitly at Pentecost (Acts 2:21), and the whole apostolic gospel then presses the question Joel leaves open — whose name? Acts 4:12 answers it: the saving "name of the LORD" on which all who call are saved is now confessed to be the name of Jesus (Acts 4:10, "by the name of Jesus Christ of Nazareth"), the very name by which the lame man was healed. This is promise-fulfillment carried on a striking divine-identity claim: the exclusive saving name of Joel's YHWH is applied without remainder to Jesus, so that to call on Jesus is to call on the LORD (cf. Rom 10:13, again quoting Joel 2:32). The telos is the preciousness of that one name: salvation is narrowed to a single name not to impoverish but to fix hope on a Savior in whom it is unfailingly secure — "no other name" is good news to the helpless, for the one name that saves is freely offered to "everyone who calls," and He is worth calling upon.
