I know it's tradition to invite the officiant to the reception, although I am 99% sure our priest will not come as the church has 2 other weddings scheduled that day after ours. There's a chance both of those couples are bringing in a different priest, but I feel it's a very small chance. Anyway, I still feel like I should extend an invitation to him, I'm just not certain how to go about doing it. Just mail him an invitation? Should I include a little note so he remembers he's presiding over our wedding (the Cathedral does at least 3 weddings every weekend, and we only met him once, so it's entirely possible he will have no idea who we are if we just mail him an invite with no note). Or would a phone call be ok?
