Praying to angels is not acceptable to the God of the Bible. Praying to Father God is the only prayers a Christian should pray.
Matthew 6
6 But you, when you pray, go into your room, and when you have shut your door, pray to your Father who is in the secret place; and your Father who sees in secret will reward you openly. 7 And when you pray, do not use vain repetitions as the heathen do. For they think that they will be heard for their many words.
8 “Therefore do not be like them. For your Father knows the things you have need of before you ask Him. 9 In this manner, therefore, pray:
Our Father in heaven,
Hallowed be Your name.
10
Your kingdom come.
Your will be done
On earth as it is in heaven.
11
Give us this day our daily bread.
12
And forgive us our debts,
As we forgive our debtors.
13
And do not lead us into temptation,
But deliver us from the evil one.
[d]For Yours is the kingdom and the power and the glory forever. Amen.
14 “For if you forgive men their trespasses, your heavenly Father will also forgive you. 15 But if you do not forgive men their trespasses, neither will your Father forgive your trespasses.
