[quote=Michael Allen;10501076**]I think we owe first allegiance to our conscience.
Should any of us do what we believe to be wrong simply because we are told to do it?
Deep within his conscience man discovers a law which he has not laid upon himself but which he must obey. Its voice, ever calling him to love and to do what is good and to avoid evil, sounds in his heart at the right moment. . . . For man has in his heart a law inscribed by God. . . . His conscience is man’s most secret core and his sanctuary. There he is alone with God whose voice echoes in his depths (CCC 1776).
Milgrim’s famous experiments come to mind.
As the catechism teaches us, our conscience must be an informed conscience. That is, steeped in Catholic teaching. You quoted the catechism correctly so that is why I wonder why you would make a statement that our first obligation is to our conscience. Our first obligation, in the words of Our Lord is: “To love your God with your whole heart, your whole mind, and your whole being. The second is like unto this: to love your neighbor as yourself.” So, our first obligation is not to our conscience but to God and His law.
