My answers are biblical, and you can’t prove otherwise, or you would have already. And as for “snark,” I can’t even hold a candle to you.
Yes, they are biblical. So is the law.
But what you need to understand is that mercy and truth came through Jesus. Christ's commentary on the law was to restore the law to it's original interpretation, and to purge it from the rabbinical corruption which turned the concession into a license.
Christ, under the law, and when restoring the law, gave no mercy, because the law has no mercy to give. But the Apostles, loosened certain things, and the one central and universal dogma was that of marriage.
Naturally, the carnal heart will do what Hillel did, and turn the concession into license. Christ, in His resroration of the law in the Sermon of the Mount, gave no occasion for desertion, or abuse, or other miseries inflicted by a churlish or odious spouse. The Apostles did, though.
And despite the other errors of Rome, an Annulment is the offshoot of that understanding.
Marriage is a blessed estate. We are called to peace. But where peace cannot abide, there can be no marriage...no matter what vow one might have made thinking otherwise. So one, according to the letter, avoids adultery. What of the murder and warring that is ongoing?
At one point, when my ex said I vowed for better or for worse, I said, That didn't mean
your worst. It was eventually she who said we needed to divorce.
You need to realize that it's your elders that are telling you that you do not understand the dynamics at play, or what was Christ's intent in His words.
But since you're all about purity...let me ask you this: You have one daughter. Are you practicing birth control?
But where birth control is used...isn't that just about getting off? Isn't it just about your strong desires, mutual though they may be? And what did Jesus say about looking upon a woman with lust? I don't see a spousal exception there.
