2:11 Lord. Christ’s humility is His glory (cf. Matt. 23:12). The “name that is above every name” (v. 9) is “Lord.” In the Septuagint (the Greek translation of the Old Testament), God’s name is represented by the title “Lord” (Greek kyrios). Christ is now acclaimed to be what He has always been, the true God (1 John 5:20). The ascription of praise embraces both the humanity (“Jesus”) and the deity (“Lord”) of Christ; He is worshiped as the God-Man. See “Jesus Christ, God and Man” at John 1:14.
God the Father. Jesus Christ is the Son of the Father. So united are the Persons of the Godhead that the act of worshiping the Son glorifies the Father. Although he does so elsewhere (Rom. 8:3; Gal. 4:4), Paul does not refer to Jesus as the Son of God in Philippians.
