We’re in So Cal. There are some pretty great megachurches around here and in San Diego too. Good theology, great workshops on marriage and family, raising kids, living a Christian life. Good/ excellent rock worship, IF you like that sort of thing.
We were Evangelical Protestants for 20 years before becoming Catholics, and we found strong believers, Spirit-filled worship, good preaching in these churches. There are plenty of small groups within them to get to know a sub-group of people very well. Great Bible teaching.
What I began to yearn for, tho, was the Eucharist at the center of things, and the Creed (vs a Mission Statement) and other ancient foundational beliefs. As a musician myself, I rarely appreciated the rock worship and always yearned for the Great Hymns, but that is secondary. The megachurches are a great place to gather in new believers and teach them the faith, and can do this with great worship and teaching how to live the Christian life — I do not find this in the Catholic church.
For me, tho, becoming Catholic has been a Journey Home, and I would not go back.
The small groups were difficult to fit into. I remember going onto the churches website to get into them only to find out that many of them didn’t exist anymore. It’s just a who do you know world (even in the church).
