Probably not a good idea to mimic evangelicals at this point. They’re quickly degenerating into either a social gospel, Rick Warren, or prosperity gospel, Joel Osteen. All apostasy. If you want some mentors, look to the house churches in China, IMHO.
I don’t think the Pope was talking about mimicking them. He was referring to their “fervor” and “zeal” while at the same time asking how such a hollow and false form of Christianity spreads just like Mormonism before the advent of the Haggards, Schullers, Tammy Bakers; Osteens, and Grahams,
