Actually, belief in the True Presence is quite humbling doctrine. The more one draws closer to Jesus Christ present in the Blessed Sacrament, the more humility one must acquire, there is no room for the proud of heart.
We receive the living glorified body of Jesus Christ, but He hides his glory and divinity from us. We are washed clean in His Blood. His Blood is upon the lintels of our souls to save us from the angel of death. In Holy Communion we have a much greater miracle than what happened in Egypt on Passover.
Once He did show me some of His glory when I received Him in Holy Communion. It is a Love that I will never forget as long as I live. There are no words that can describe it.
The Bible disagrees with you on this as it does so much of what you believe.
And one called out to another and said, "Holy, Holy, Holy, is the LORD of hosts, The whole earth is full of His glory." In the year of King Uzziah's death I saw the Lord sitting on a throne, lofty and exalted, with the train of His robe filling the temple. Seraphim stood above Him, each having six wings: with two he covered his face, and with two he covered his feet, and with two he flew Isaiah 6:1-4
"For the earth will be filled With the knowledge of the glory of the LORD, As the waters cover the sea Habakkuk 2:14
O LORD, our Lord, How majestic is Your name in all the earth, Who have displayed Your splendor above the heavens! Psalms 8:1
The heavens are telling of the glory of God; And their expanse is declaring the work of His hands. Psalms 19:1 NASB
But being full of the Holy Spirit, he gazed intently into heaven and saw the glory of God, and Jesus standing at the right hand of God; Acts 7:55
And an angel of the Lord suddenly stood before them, and the glory of the Lord shone around them; and they were terribly frightened. Luke 2:9
We are washed clean in His Blood. His Blood is upon the lintels of our souls to save us from the angel of death.
If we are washed clean in His Blood, and we are, then the Roman Catholic doctrines of mortal sins, loss of salvation, purgatory are all negated.
