“Go and sin no more.”
And this is the whole point. Isn’t it? The scriptural injunction is to condemn the sin not the sinner. By knowingly renting to gay couples is not one complicit in the celebration of a sin?
Wouldn’t the proper imperative be: “Yes, we’d rent to you on condition you don’t engage in gay sex” But the law will not allow for this imperative- it would be criminal discrimination.
Is it a sin to show kindness to sinners?
