I can’t imagine that EPC meant Evangelical Pentecostal Catholics.
First, that’s a term foreign to Catholicism, where the movement is known as the Catholic Charismatic Renewal (CCR).
Second, the migrants in question have very POOR family ties and are usually almost completely unchurched.
Lastly, the book you reference isn’t about Catholic churches.
That’s correct. It’s not about Catholics. It’s about a study.
