Holy cow! It is truly unfortunate that this goes on. My spouse and I do wedding rehearsals, and we remind the wedding party of who is able to receive communion. If there was no consecration, then communion should not be offered. There is a beautiful rite of marriage that is done outside of mass which we strongly recommend when both parties are not Catholic and no communion may be offered. Definitely this was a case of flagrant abuse. Pray!
The rite of marriage outside of mass is also used when one party is catholic and the other is not. In those cases, there is not a consecration, but there is communion for the catholics using pre-consecrated species. Also there are times when there are 2 catholics being married and there is no priest available, and a deacon is given facilities to marry the couple, again there is no consecration but there is communion offered.
It is good that you tell the people who may recieve communion, and the couple should definitely inform their guests, but the priest or deacon should make a short announcement too.
Of course we don’t know if the couple were both catholic or not because the original poster didn’t state. BUT the priest may have brought pre-consecrated hosts, which is acceptable, but giving it to everyone is not. ALSO
In order to do a wedding outside of the church, permission is needed from the bishop, but once that permission is given, a Mass can be said outdoors which if it were a Mass would include a consecration.
But I am assuming, from the original post that the priest had pre-consecrated hosts with him. The only problem I see in the whole thing was that it was given to everyone, and not just the faithful.
