Faith Will Tell Us Christ Is Present,

[it Is Appropriate That The Body And Blood Of Christ Be Truly Present In This Sacrament] Because Of The Perfection Of The New Covenant. The Sacrifices Of The Old Covenant Contained The True Sacrifice Of Christ's Passion Only In Symbol....therefore It Was Necessary That The Sacrifice Of The New Covenant, Instituted By Christ, Have Something More, Namely, That It Contain Christ Himself Who Has Suffered And Contain Him Not Only In Symbol But In Reality.

Just As A Man Cannot Live In The Flesh Unless He Is Born In The Flesh, Even So A Man Cannot Have The Spiritual Life Of Grace Unless He Is Born Again Spiritually. This Regeneration Is Effected By Baptism: "unless A Man Is Born Again Of Water And The Holy Spirit, He Cannot Enter Into The Kingdom Of God" (jn 3:5)

Unbelief Is The Greatest Of Sins.

He (mohammed) Seduced The People By Promises Of Carnal Pleasure To Which The Concupiscence Of The Flesh Urges Us. His Teaching Also Contained Precepts That Were In Conformity With His Promises, And He Gave Free Rein To Carnal Pleasure. In All This, As Is Not Unexpected; He Was Obeyed By Carnal Men. As For Proofs Of The Truth Of His Doctrine, He Brought Forward Only Such As Could Be Grasped By The Natural Ability Of Anyone With A Very Modest Wisdom. Indeed, The Truths That He Taught He Mingled With Many Fables And With Doctrines Of The Greatest Falsity.

The Blessed Eucharist Is The Perfect Sacrament Of The Lord's Passion, Since It Contains Christ Himself And His Passion.
