I'm Episcopalian too. We go about twice a month. It's just laziness on my part, to be honest. I'm a night owl. A nine-ten start time for Eucharist just doesn't mix well with a 2AM bedtime.

It's kind of difficult with three young ones, but we lucked upon a church that doesn't bat an eye when they get loud during the service. My usual comment about St George's: You've
got to love a church where you can open the walls.
While it is true of course that I can worship God anywhere...Well, coffee hour is lonely when it's only me.

And a church provides opportunities for outreach that just don't exist for the solitary worshipper, not without great difficulty. I'm not into St George's enough to know what all charities they have their hand in, but my church back home not only hosts AA meetings but is an active supporter of the local battered women's shelter, one of the homeless shelters, and Christian Assistance Ministries, which has a clothes closet, a food bank, and also provides monetary assistance (like, for paying your bills). They also regularly run mission trips down to Honduras, and when the Episcopal church does a mission trip they take construction equipment and medicines.

My abilities are much magnified through my involvement with the church. I don't make enough money to do much of anything on my own, but the church offers the opportunity to get my hands involved as well.
I couldn't deal with spending hours upon hours there, though. If my soul can't be saved in an hour, it's not gonna be saved in three.

I'm good for sixty minutes on Sundays (not counting fellowship afterwards, of course), and maybe an occasional Bible study class or service Wednesday nights, but I couldn't go spend two or three hours at church every night like my sister does.
