My pastor one Sunday advised those who are married outside the Church to keep attending Mass regularly even though they cannot receive Communion. He said that they still benefit from attending Mass, and that one day circumstances in their lives may change and they can marry in the Church and begin receiving Holy Communion once again. My sister was married outside of the Church 25 years ago, and she and her husband, who is not Catholic, both attend Mass every Sunday without fail.
Why would they??? You're religion teaches that without eating the wafer, there is no eternal life...Why waste their time???
Your Pastor sounds like a wise man.
