Yes, I pray to angels.

A Protestant asked: 

Do you pray to angels?

Yes.  Here's an example:

Saint Michael the Archangel,
defend us in battle.
Be our protection against the wickedness and snares of the devil.
May God rebuke him, we humbly pray;
and do Thou, O Prince of the Heavenly Host -
by the Divine Power of God -
cast into hell, satan and all the evil spirits,
who roam throughout the world seeking the ruin of souls.
Amen.

Why don't you?

Joshua 5:14
King James Version (KJV)¹⁴ And he said, Nay; but as captain of the host of the Lord am I now come. And Joshua fell on his face to the earth, and did worship, and said unto him, What saith my Lord unto his servant?

That is St. Michael, whom Joshua spoke to and honored. The Captain of the Host of the Lord.

Sincerely,

De Maria
