Greeks’ traditional religion did not see its gods as their fathers. When a Greek became a Christian, they accepted that the One and Only Supreme God was their Father.
The pronoun “from” which is applied to “God our Father” is also implied to be with “the Lord Jesus Christ”, so that it would also read, “from the Lord Jesus Christ”. Grace and peace come from God the Father and the Lord Jesus Christ. The grace and peace I receive through the Holy Spirit is a gift of the Father and Son.
Paul, in verses 1 and 2, uses the title “Jesus Christ” from the Greek “Iesous Christos” (and vice versa). Here, Paul uses the phrase “Lord Jesus Christ” from “Kyrios Iesous Christos”.
Greek culture traditionally did not believe any of their pantheon of gods were lords, let alone a Supreme Lord. They believed their gods were subject to fate just as humans were. Greeks did not worship a god as Christians and Jews do. Rather, they believed their gods had powers and abilities that humans do not have, but none of them were the creator of the cosmos (universe). The Greeks attempted to win the favor of one of their gods to convince that god to grant them a gift and/or favor with their unique power, not much different from the comic book group of heroes today. Which god they sought favor from depended on the special power the god had.
Christianity teaches the truth through the Holy Spirit. A Supreme God exists for eternity and beyond, God the Father. He has an eternal Son who is Lord of all, creator of all, including all humans. Jesus is the name God the Father, through the Spirit, gave to him when he came to the earth in the form of a human to redeem His people from sin and death. Through grace, not merit, Lord Jesus Christ, and God the Father give peace of soul.
