Does this make the children bastards in the church which annulled the parents marriage?
I don’t know the answer to that question, as a matter of fact, to be honest.
However if one accepts the definition of “bastard child” as one concieved as a result of willful fornication I would say “no”, as, at the time, (I think it’s safe to assume) the two believed they were married so they did not “willfully” commit fornication.
This is my opinion of the situation.
No it does not. The parents had a civil marriage, the Church is dealing only with the Sacrament of Holy Matrimony.
Ok, if you want to put it that way. That’s kind of a mean slur on innocent children, though. The parents were also considered married according to the civil laws of the state, so the kids are not the children of unwed parents under the civil laws.
No
NO, it does not. Legitimacy for children is imparted by the STATE by way of the marriage license. If a couple has children and is divorced legally, that doesn't make their children 'bastards', so why should the statement of nullity of a Sacrament, which had nothing to do with 'legitimacy' of any children born in that marriage?
