There’s a definitional problem here: “a homosexual” can mean a person afflicted by a besetting temptation to engage in homoerotic behavior, whether or not he or she yield to that temptation, whether or not he or she, should he or she yield to the temptation feels remorse and repents to return to struggling against the temptation. It can also mean one who abandons him- or herself to such temptations, which is surely what St. Paul was writing against, since a sodomite is not one tempted to sodomy, but one who commits sodomy.
If never yielding to temptation is the standard for being a Christian, well, then the only Christians in the world are a handful of monks and nuns who have managed not only to keep their vows by God’s grace, but overcome all envy, pride, anger. . . and the rest of us are just wannabes or poseurs. Even monastics when asked what they do, reply “we fall down, and we get up, we fall down and we get up” referring to falling into sins and repenting.
One can be a Christian regardless of what one’s besetting temptations are, but if one is a Christian, does not abandon oneself to those temptations, one repents when one falls into sin, and does not justify one’s sin on the basis of being afflicted with a besetting temptation, and does not claim that one’s sin isn’t sin, much less try to claim that it is actually good.
“and does not justify one’s sin on the basis of being afflicted with a besetting temptation, and does not claim that one’s sin isn’t sin, much less try to claim that it is actually good.”
Precisely, I agree.
