Here's the passage:
KVJ Php 2:11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Westcott and Hort / [NA27 variants] καὶ πᾶσα γλῶσσα ἐξομολογήσηται ὅτι ΚΥΡΙΟΣ ΙΗΣΟΥΣ ΧΡΙΣΤΟΣ εἰς δόξαν θεοῦ πατρός.
It is very common to hear people refer to "God the Father, God the Son and God the Holy Spirit" in a way that suggests that "God" is a category and "the Father", "the Son" and "the Spirit" are subcategories.

Jud_1:1 Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:
