If I went Maronite I wouldn't be leaving at all, would I? I left the Episcopal church because of the immorality, but that didn't mean I naievly thought there was none in the Roman Catholic Church. It was because I decided that the RCC was the true repository of Christianity on earth. Furthermore, though individuals, too many of them, behave in an immoral way, our church is not afraid to say what's wrong is wrong. That was very important.
(1) If you went to a Maronite Catholic Church you would not be breaking communion with with Pope and the rest of the Church, founded by Christ on the Rock of Peter and the Apostles.
(2) Our church is not afraid to say what's wrong is wrong. At least, dadgummit, when we Catholic sinners sin, we know damn well that we're sinning.
And that IS an advantage. It makes it harder for us to fool outsleves into thinking everything's OK, and makes it possible for us to repent.
