My brother goes to a HUGE "Evangelical" church... and yes, while they gain huge numbers of people every week (most from the unchurched), they also loose enormous numbers every week. I mean, how can you have 100 first time local guests every week (and they do)... and not be growing? My bro is an exception; most of their "converts" are non-practicing Christians - many of them new to Christianity. So in that sense, they do ENORMOUS evangelism, bringing LOTS in.
but yes, they don't tend to retain them for long. I SUSPECT (but I don't know) many find it.... empty. I don't know where all their "exits" go.
My Lutheran parish is about half former Catholics. Most of the rest are cradle Lutherans - but there are converts from Baptists and other mainstream churches, but not too many "Evangelicals." One couple, a Hispanic family, were both raised Catholic but returned to Christianity via a big Evangelical church in town and then became Lutherans (that was before I joined this church).
My Catholic parish had a FEW converts from other backgrounds. Amazingly few.... I'd guess 90% or so were cradle Catholics. The "converts" that I knew of were all Protestants or unchurched who married a Catholic and, for the sake of unity and the family, became Catholic (a couple I'm thinking of, very passionately Catholic). There's a popular joke of sorts in Catholicism that Catholic evangelism is all done by good Catholic wives - and I witnessed a lot of truth in that. We had a fairly significant RCIA group every year (that's the official church membership/adult confirmation group in Catholicism - basically adults converting) but it was always spouses. Obviously, this doesn't make up for all the exits: there are some 30 MILLION former Catholics just in the USA right now: Ex-Catholics, people who LEFT the RCC, are the second largest religious group in American - roughly the size of the two largest Protestant denominations combined, almost as large as all of Evangelicalism in America combined, EX-Catholics (like me and a few others here at CH) so I don't think they are flooding there, although I'm sure a few do.
