A couple of points to consider when discerning demagoguery from piety, under the rationalizations of evangelization and the presentation of the One, True Faith:
- Is the piety manifest being covertly or overtly used to increase support for one or another political party?
- Does the inherent message set forth address the fullness of the Christian Faith and its doctrines? Or is it being subtly skewed by omission, if not outright commission, in order to proof-text support for a personally-favored party, NGO, or association?
The Devil is the father of lies and he knows both Scripture inside out and the sayings of all the saints.
Discern contexts carefully in order not to end up deceived.
