Justin Martyr (c. 155) talks about portions of bread and wine/water being sent out to those who were absent, but it’s clearly an extension of the community event. They wouldn’t have had “their own service” if they weren’t present with the church; the bread and wine/water they received was the Lord’s Supper because it was an extension of the church’s celebration, not their own. Ignatius (c.115) is pretty clear about the church-gathered as the place for baptism and the Lord’s Supper.

I used to go serve communion with my dad sometimes to people who couldn’t get out to church, and it always felt like an extension of what we did Sunday as a body – a very beautiful thing. But I’ve never understood the exclusive taking of the Lord’s Supper by bride/groom at a wedding when the rest of the church sits back and watches. Aren’t we all in this together? Isn’t the participation of the church community essentially what a wedding ceremony is for anyway – to have the church, as an ecclesial authority, affirm the couple’s covenant? We can’t all light a unity candle (nor should we), but we all drink from the same cup and share in the same bread as a sign of unity with Christ and each other.
