Greek Key Terms:
Context: Romans 10:9-13 explains the universal availability of salvation through faith in Christ. Paul quotes Joel 2:32 in v. 13: "Everyone who calls on the name of the Lord will be saved." In Joel's context, "the Lord" is Yahweh. But in Paul's context (vv. 9-10), calling on "the Lord" is calling on Jesus—confessing Him as Lord, believing God raised Him from the dead. Paul seamlessly applies a Yahweh text to Jesus, equating calling on Jesus with calling on Yahweh for salvation.

Connections:
Connection Method(s): Promise-Fulfillment, Redemptive-Historical Progression — Joel 2:32's eschatological promise that "everyone who calls on the name of the LORD will be saved" is fulfilled when Paul applies it to calling on Jesus' name, identifying Christ with Yahweh as the object of saving invocation.
Christological Connection: Romans 10:13 is Paul's explicit identification of Jesus with Yahweh. The logic is inescapable:
This is reinforced throughout the NT. Acts 2:21 quotes Joel 2:32 at Pentecost; Acts 2:38 commands baptism "in the name of Jesus Christ." Acts 9:14,21 defines Christians as "those who call on this name" (Jesus). 1 Corinthians 1:2 addresses "those who call upon the name of our Lord Jesus Christ." The early church was characterized by invoking Jesus' name in prayer and worship—an act that would be blasphemous idolatry unless Jesus shares the divine identity.
Paul is not abandoning monotheism (Rom 3:30: "God is one"). He is redefining it Christologically. The one God exists as Father, Son, and Spirit. To call on the Son's name is to call on Yahweh, because the Son shares the one divine identity. Romans 10:13 establishes that salvation comes through invoking Jesus' name—the same act Joel describes as calling on Yahweh for deliverance.
