Praying to the mother of Jesus Christ is not part of Trinitarian Christianity.
But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking. Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him." -- Matthew 6:6-8"But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
To elevate a mother is to devalue the Father.
Joh 10:9 I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
