Cruz wasn't in church when he said this. He was at a campaign rally.
From Drudge: At a stop Saturday at Darrell's Place in Hamlin, Iowa, Cruz urged his supporters to "awaken the body of Christ that we may pull back from the abyss."
It wouldn't have been out of place and seen to be pandering if he'd actually been in a church.
OK, then. Christians should never practice their faith outside the four walls of their churches. They should never reference Scripture in “the real world.” Doing so only makes you come across as “creepy.”
Christians should just put a cap on their faith. Maybe it’s best for them to vote for billionaire vulture capitalists, and to just shut up about Jesus already.
