Thank you Ron.
One additional favor, do you have or could you bring Magisterial documents or Cannon Laws supporting the answers for #1 and #2 ?...
The situation is this, apparently, a priest told a group of people the opposite for #1 & #2 in a retreat. I wasn't in that retreat, but a person from that group of people, who by the way are caddle Catholics, has told me that the priest has taught them that marriage for cases #1 & 2 are invalid (or null). It seems as they have believed what the priest has allegedly told them. If I tell that person or anyone from that group that the priest was in error in those cases (if it's true that's what the priest told them), they would not believe me; however, if I bring back up, Magisterial documents, supporting the contrary, they would re-consider.
