For this cause (anti toutou). “Answering to this” = heneken toutou of Gen 2:24, in the sense of anti seen in anth' hōn (Luk 12:3). This whole verse is a practical quotation and application of the language to Paul’s argument here. In Mat 19:5 Jesus quotes Gen 2:24. It seems absurd to make Paul mean Christ here by anthrōpos (man) as some commentators do.
