Circumstances do not change morality. An easy way to tell true theology from fake, is to apply this rule. If something is A True and Living icon, then it stays true regardless of circumstances. Our marriage vows say In sickness and in health, for richer or poorer, until death do we part. Those of us who hold true to those vows, no divorce is possible due to circumstances.
The Archdiocese of Washington DC put forth their answer to Amoris Laetitia this week, and this review on The Catholic Thing is well worth reading. It points out that the subjective conscience, being without full understanding of Church Teaching, is actually incompetent to judge morality. Moral Order exists for a reason. Free will, while a great gift from God, is also a very dangerous gift from God, Moral Order, when you enshrine it in your marriage and in your home, keeps your marriage safe from the very abuses I've written about in previous articles. Far from being burdensome as most imagine, Moral Order frees us to truly love, as opposed to just "accept" and "tolerate" that which is wrong. And that, as you start your married life together, is an invaluable lesson- children need boundaries, and so does your marriage.
