1 Coríntios 6

15 Do you not know that your bodies are members of Christ himself? Shall I then take the members of Christ and unite them with a prostitute? Never!

16 Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, "The two will become one flesh." [2]

17 But whoever is united with the Lord is one with him in spirit. [3]
