The problem is that the “challenge” is really no more than a self-defined truism. The response by Catholics to any Catholic who converts to a Protestant faith will be: (1) he didn’t truly understand the Catholic faith or (2)he acted on the basis of personal sinful motives. Like many things, Catholics simply “define themselves” out of the problem.
But do you know of
any case where a Catholic converted to the Episcopal church because he or she became convinced through a study of history and reading of the ECF’s that the Episcopal church was **the true church **established by Christ and the Apostles? That’s the challenge.
People leave the Catholic Church for a variety of reasons. Some know the faith well, some don’t know it at all.
But Dr Beckwith’s conversion story is one typical to many other testimonies we see with converts to the Catholic faith. I just don’t think we see many Catholics converting to Protestantism for the same reason he did.
For example, Dr Beckwith was an Evangelical who loved his faith, knew it well, had a good reputation in the Evangelical world but was willing to give it all up because through a study of history and the Fathers, he was convinced the Catholic Church was the true Church and had divine authority.
From my experience and the testimony of Catholics who convert to Protestantism, most Catholics who convert to Protestantism stop believing that there is a “true Church.” They usually adopt the non-Catholic idea of the church as the invisible body of true believers.
But Fr Ryland may be wrong. If you know of
any examples where a Catholic studied history and the Fathers and identified another Christian body as the “true” church, then converted to that church, please let us know.
