"If the Catholic Church teaches that remarried Catholics may receive communion, you are confident in that answer?"  

The Church has the fall back position defined, and that is the supremacy of one's well formed personal conscience. Now, we can argue just exactly what is meant by 'well formed', but in the end we stand alone before God, and not holding any Pope's hand.   At that point, I will do what Pope Francis has asked, and trust in God's infinite mercy....and I don't actually mean that as a joke.  It's my truth.  I believe in a God that has to know we poor humans flail through life as best we can given the circumstances of our birth and the junk life throws at us and He will show us a level of mercy we probably don't deserve.  I am hoping God is much bigger than Church teaching.
