It took Enoch a moment before he realized he'd never summoned his armor in front of people who didn't already know before - he couldn't on the search, everyone in the Tower (that is, the Grigori's) knew about it, and it just never happened in Meridian.

"It's a blessing from God, to protect me." Close enough. He didn't want to go into the full story right now. He didn't know whether he should be grieving or angry and being torn between the two wasn't doing him any favors.
