Mass Indoctrination Day 3 _The Doctrine of prayer

Although I couldn’t join the mass indoctrination of the day 3 from the beginning, but what I understood was that the doctrine is based on prayers. I joined up in the part where he was teaching about the rosary used by the Catholic Church.
I learnt that it is wrong and unbiblical to use the rosary as means of prayers because it has no biblical root. He further taught about the history of the rosary in the Catholic Church that St. Dominic de Guzman is the source of the Rosary in the year 1214. That was 1200 years after Jesus has ascended to Heaven. The doctrine of the Bible does not permit the Rosary because it was not taught in the Bible.
(Isa 65 vs 24; Mathew 6 vs 7- 8)I learnt that we should avoid repetitive prayer because God is not deaf and that the one we pray to is the Almighty.
i learnt from the teaching in (mat 6 vs 3-6) there is a posture for prayer and when we should pray it should not be a means of show off. only hypocrite loves to pray standing. However mk 11 v 25 makes also clarify us that if we must pray standing , it should not be like the hypocrites.the early Christians prayed kneeling down (act 20 vs 36).
when a man is kneeling down it means to fold the knees source

mt 26 vs 39 , i learnt tha, at Gethsemane, Christ fell on his face kneel down and fell on the ground which is an act of humility and worshiping God. (psm 95 vs 6) to kneel is synonymous to bow down. bowing sown means to show intense respect to God, I learnt that in Greek it is called kaw-rah. and the bible was written in Hebrew and in Greek so no priest in latin will teach this accurately.
i learn that keeling down should be horizontal or vertical source

An instance of knowledge, if you want to take request from the president, a king, the Queen, you bow your face your face. So christian can pray standing but don not love praying standing in order to show respect. For instance, you can not bow the knees in the mud, or a dirty area but you can still pray. There are pastors and people who when they pray, they wave there hands but this is not in the Bible.
Brother Eli pleaded that that the teaching is not to get anyone angry because He is teaching the Truth. With prayers alone, thousands of churches won't come to agreement.
1 cor 11 vs 4-5 i have learnt that man ought not to pray with his Head covered and when a woman prays she should cover her Head. We all have Head, God is the head of Christ ; Christ is the Head of Man and And Man is the Head of the Woman. In the true Church a woman should have a covering her Head because she is under the her head which is the man, the man is the symbol of Christ
1 cor 11vs 7-10 it is clear that the apostle teaches that a woman should cover head as a symbol of her husband. Why should the head not be covered by Man?
Bro said tomorrow we will continue with the doctrine of prayer as we have learnt today will learn that our prayer should not be repetitive. Because even before we open our mouth he already know our hearts.

Finally, I appreciate the Doctrine of Bro Eli and I wish to know also learn more as regards praying in tongues too.
God bless the Word of God in our Hearts
