All I'm saying is that it doesn't surprise me. This kind of thing happens all the time with weird outcomes. If he's happy where he is, fine, it's between him and God. However, his basis for theological conversion seems to be one of his own failings - not the fallibility of his former faith.
And of course there are more defections from the Catholic Church to Protestant Churches, so I am not sure what this series if postings is suppose to show.
His crisis was spiritual and has to do with the lack of devotional life:
While I was gaining all this knowledge and continually fueled by a desire to become a great teacher, I was also letting my growth in holiness decline
His ministry work was commendable; who would disagree with this objective:
to take Baptists back to the practices and beliefs of the Baptist founders, which, I believed at the time, to be synonymous with the beliefs and practices of the early Christians.Absorbed in this struggle, he admits to a neglect of his marital life. It is a consequence of the Baptist faith's deficiencies, not the cause of his leaving it. He had two children by then. Further, whatever that neglect was, the family obligations were a factor in keeping him in the Baptist ministry, as he needed a job.
I think, you are simply unprepared to face the fact that reasonable, academically gifted, devoted to the ministry people would discover the Christ in the Eucharist and the veracity of Catholic historical root, and so you try to find fault in this man.
