One of the strongest affirmations of the divinity of Christ occurs in Greek Hamburg Papyrus (IX, 13): εἷς Χριστὸς Ἰησοῦς καὶ ἄλλος οὐκ ὑπάρχει· This sentence resembles 1 Cor 8.6: ἀλλ’ ἡμῖν εἷς θεὸς ὁ πατὴρ ἐξ οὗ τὰ πάντα καὶ ἡμεῖς εἰς αὐτόν, καὶ εἷς κύριος Ἰησοῦς Χριστὸς δι’ οὗ τὰ πάντα καὶ ἡμεῖς δι’ αὐτοῦ. AP IX, 13 shares three common themes with 1 Cor 8.1-6: These are: (1) A polemic against idolatry: both argue that idols represent false gods: The Acts of Paul says they are empty; 1 Cor argues that they have no real existence. (2) Both raise the language of the Shema, in order to affirm what R. Bauckham calls Christological monotheism. The Lord Jesus Christ is the one Lord of the Shema and affirmed thus as the one eternal Creator. (3) Both texts affirm creation theology–that God created the heavens and the earth and humanity.
