I am an ex catholic myself and I went to Catholic grade school at St Mary's parish and catholic high school at St James High School, in Grand Forks, North Dakota, from 1954 to 1966, so you can see it has been a ton of years ago. I cannot recall if any of them ever told me that Mary was divine. I simply do not remember. They did, however, teach us to pray to Mary, like the rosary, or after embarrassing myself in the confessional, so does the fact that we were taught to pray to her, make her divine? I don't know, but of course, I don't do that now. I always enjoy our catholic high school class reunions. There are 2 others, like me, and we have developed some friendly rivalries over the years, with some of the class mates we keep in touch with occasionally. We have fun talking about doctrine. The other two guys are full time preachers. Me? I spent 20 years in the USAF and 25 years in CDCR, at San Quentin, and Solano at Vacaville, CA. BTW, my degree was in air traffic control, of which I was real darned good at, even if I do say so myself. Later bro.
It attributes to her the uniquely Divine position of being the object of prayer to Heaven, which always directly to God in the over 200 prayers in the Bible which God provided for us, and thus ascribes to her the uniquely Divine ability of hearing virtually infinite amounts of prayer addressed to her.
The Scriptures do not sanction religiously bowing down to any statue in supplication, and the Lord's instructions on who to pray to was "our Father who art in Heaven," not "our Mother", the former being what the Spirit also cries to, "Abba, Father," Gal. 4:6; not "Mama, Mother." The fact that the Lord Jesus is prayed to is a testament to His Deity, and He alone is set forth as the only Heavenly intercessor btwn God and man (1Tim. 2:5).
In addition, note that many Catholic Marian attributions much parallel even that of Christ:
For in the the Catholic quest to almost deify Mary, it is taught by Catholics*,
as Christ was sinless, so Mary was;
as the Lord remained a virgin, so Mary;
as Christ was called the Son of God, indicating ontological oneness, so Mary is called the Mother of God (which easily infers the same, and is not the language of Scripture);
as the emphasis is upon Christ as the Creator through whom God (the Father) made all things, including Mary, so it is emphasized that uniquely to her, Jesus owes His Precious Blood, shed for the salvation of mankind, (the logic behind which can lead back to Eve);
as Catholics (adding error to error) believe Christ gave His actual flesh and blood to be eaten, so it is emphasized that Mary gave Him this, being fashioned out of Mary's pure blood and even being kneaded with the admixture of her virginal milk, so that she can say, "Come and eat my bread, drink the wine I have prepared" (Prov. 9:5);
as Scripture declares that Christ suffered for our sins, so Mary is said to have done so also;
as Christ saves us from the condemnation and death resulting from the fault of Adam, so it is taught that man was condemned through the fault of Eve, the root of death, but that we are saved through the merits of Mary; who was the source of life for everyone.
as the Lord was bodily ascended into Heaven, so Mary also was;
as Christ is given all power in heaven and in earth, so Mary is surpassing in power all the angels and saints in Heaven.
as Christ is the King of the saints and over all kings, (Rv. 15:3; 17:14; 19:16) so Mary is made Queen of Heaven and the greatest saint, and that Next to God, she deserves the highest praise;
as the Father made Christ Lord over all things, so Mary is enthroned (all other believers have to wait for their crowns) and exalted by the Lord as Queen over all things;
as Christ is the express image of God, and highly exalted above all under the Father, having the primary position among all creation, so Mary is declared to be the greatest saint of all, and the first of all creatures, and as having a certain affinity with the Father, with a pre-eminent resemblance which she bears to the Father;
as Christ ever liveth to make intercession for the saints, so is Mary said to do so;
as all things come from the Father through the Son, so Mary is made to be the dispenser of all grace;
as Christ is given all power on Heaven and on earth, Mary is said to have (showing some restraint) almost unlimited power;
as no man comes to the Father but through the Son, so it is taught that no one can come to the Son except through Mary in Heaven;
and as the Lord called souls to come to Him to be given life and salvation, so (in misappropriation of the words of Scripture) it is said of Mary, He that shall find me shall find life, and shall have salvation from the Lord; that through her are obtained every hope, every grace, and all salvation. For this is His will, that we obtain everything through Mary.
And as Christ is given many titles of honor, so Mary also is, except that she is honored by Catholics with more titles than they give to the Lord Himself!
Mary was a holy, virtuous instrument of God, but of whom Scripture says relatively little, while holy fear ought to restrain ascribing positions, honor, glory and powers to a mortal that God has not revealed as given to them, and or are only revealed as being possessed by God Himself. But like as the Israelites made an instrument of God an object of worship, (Num. 21:8,9; 2Kg. 18:4) Catholics have magnified Mary far beyond what is written and warranted and even allowed, based on what is in Scripture.
In addition, although (technically) Mary is not to be worshiped in the same sense that God is worshiped, yet the distinctions between devotion to Mary and the worship of God are quite fine, and much due to the psychological appeal of a heavenly mother (especially among those for whom Scripture is not supreme), then the historical practice of Catholics has been to exalt Mary above that which is written. As the Catholic Encyclopedia states, "By the sixteenth century, as evidenced by the spiritual struggles of the Reformers, the image of Mary had largely eclipsed the centrality of Jesus Christ in the life of believers." (Robert C. Broderick, ed., The Catholic Encyclopedia, revised and updated; NY: Thomas Nelson Publishers, 1987, pp.32,33)
The practice of praying to departed saints and Mary was one that developed, helped by pagan influences, for Scripture provides no example of any believer praying to anyone in Heaven by the Lord, and reveals that doing otherwise was a practice of pagans, including to the Queen of Heaven. (Jer. 44:17,18,19,25). The Catholic Encyclopedia admits that a further reinforcement of Marian devotion, was derived from the cult of the angels, which, while pre-Christian in its origin, was heartily embraced by the faithful of the sub-Apostolic age. It seems to have been only as a sequel of some such development that men turned to implore the intercession of the Blessed Virgin. This at least is the common opinion among scholars, though it would perhaps be dangerous to speak too positively. Evidence regarding the popular practice of the early centuries is almost entirely lacking..., (Catholic Encyclopedia > Devotion to the Blessed Virgin Mary) Yet, as expected, it imagines this practice came from the apostles and NT church, but which never exampled or instructed it, and instead showed that the believer has immediate access to God in the Divine Christ, (Heb. 10:19), who is the all sufficient and immediate intercessor between God (the Father) and man. (Heb. 2:17,18; 4:15,16) To the glory of God
Thank you for being the only ex-Catholic to answer, and to do so with out being insulting.
