Gospel Principles, pg. 81; “If a man does not have the priesthood, even though he may be sincere, the Lord will not recognize ordinances he performs (see Matthew 7:21-23).”
Galatians 3:10-13; “For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them. 11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. 12 And the law is not of faith: but, The man that doeth them shall live in them. 13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree.”
The Lord is not going to recognize your false priesthood, sorry to say.
