My brother is a deacon in Montreal.
He can only preside at weddings in the parish he is assigned to, and then only in the Church itself. He is not allowed to marry someone in a park or any other building or location.I didn’t realize there was a difference between USA and Canada. There is the requirement of “delegation” whether the presider of the marriage is a priest or a deacon; any time a cleric witnesses a wedding outside of his assignment it is required to get the delegation from the pastor of the territory you would be visiting. Without this delegation the marriage would be invalid. So my question for you is, are priests and deacons prohibited from operating outside of their assigned area even with delegation?
If there is a mass the priest usually presides.This is correct, however the deacon if so requested by th ecouple would preside over the nuptuals. One other thought, a communion service for a wedding without a Mass is not allowed. In other words, I cannot preside over a wedding that includes a communion service just because I am not a priest. If the ceremony is to include communion it must be in a Mass. That may be particular to my home diocese, but I do not think so.
Also he cannot perform purely civil marriages, or marry those who are unable to marry in the Church.
