October 2, Memorial Feast of the Guardian Angels
No evil shall befall you, nor shall affliction come near your tent, for to His Angels God has given command about you, that they guard you in all your ways. Upon their hands they will bear you up, lest you dash your foot against a stone.
Psalm 91: 10-12
Seems like an irrelevant question, because the Devil seems like an irrelevant question. But to disregard the devil is to disregard the Bible — is to disregard Christ.
