Major problem here. If you still have the sinful desire it is still a sin. Jesus said that even looking upon a woman for adulterous purposes is sin-hanging on. Matthew 5:28 (AMP) “But I say to you that everyone who so much as looks at a woman with evil desire for her has already committed adultery with her in his heart.”
So you can gloss over her statement all you wish and not be rid of the real issue – lust retained is sin retained and has not one whit to do with diversity.
Wheaton College should know better – that to compromise one jot or tittle of the Word is to structurally damage the whole edifice of their reason to exist.
