EWTN Catholic Q&A
Question from lt on 10-31-2012:

I'm distrustful of angels since the Devil can disguise himself as an angel. How come so many people in the Bible trust angels? Should we be careful if ever we see an angel? Why do we have guardian angels if God has "every single hair in our heads counted" and is all powerful?

Dear Le,

Follow the Church. She trusts in the angels St. Michael and St.Gabriel. No one can do better than than.
