Stephen Murphy left the church after being exposed to anti-Mormon content. After much studying and researching, he returned.

"I remember my dad, he sent me an apologetic video -- initially I was like 'dad I don't want to listen to this pseudo scholarship, this mental gymnastics the church isn't what it claims to be, come on give it a rest.' He was like just watch it. I sort of recognized that I'm not being very open-minded, I'm not willing to listen. I'd already come to a firm conclusion so I was like fine I'll watch it. It was by a guy called Bruce Porter and it was about the connections and correspondences and parallels between our temple endowment and ancient Egyptian temple rituals. If I'm being intellectually honest and consistent, just as I couldn't deny that there are things which are similar - if not identical, between a Masonic ritual and the temple endowment, there were things which correspond quite well. So I was like, 'okay, I can understand why a true believer they might think that the temple endowment is like a restoration of an ancient temple ritual.' So that sort of sparked some curiosity and I started to explore more evidence for things like this."
