The Bible was canonized before the RCC started instituting extrabiblical doctrines, methodology and traditions.
The veneration of Mary started in the 4th century. Lighting candles for the dead started in the 4th-5th century. Cardinals came about in the 8th century. Holy water started in the 9th century. Vernation of saints started in the 10th century. Confessing to a priest started in the 11th century. Calling a priest "Father" started sometime in the late Middle Ages. The belief in the transubstantiation of the Eucharist started in the 12th century. Roseries started in the 13th century. That's just the few things I know of off the top of my head and looked up.
You have picked up a lot of false information about the Catholic Church. For example, confession to a priest
DID NOT start in the 11th century. Here are some historical quotations:
"Just as a man is enlightened by the Holy Spirit when he is baptized by a priest, so he who confesses his sins with a repentant heart obtains their remission from the priest." – Saint Athanasius of Alexandria (
d. 180)
In addition to these kinds of forgiveness of sins, albeit hard and laborious: the remission of sins through penance…when he [the sinner] does not shrink from declaring his sin to a priest of the Lord and from seeking medicine. – Origen (
A.D. 244)
It seemed likewise impossible for sins to be forgiven through penance; yet Christ granted even this to his Apostles, and by His Apostles it has been transmitted to the offices of priest. – Saint Ambrose (
d. 397)
Priests have received a power which God has given neither to angels nor to archangels. It was said to them: “Whatsoever you shall bind upon earth shall be bound in heaven; and whatsoever you shall loose, shall be loosed” [Matt 18:18]. Temporal rulers have indeed the power of binding; but they can bind only the body. Priests, however, can bind with a bond which pertains to the soul itself, and transcends the very heavens…Whatever priests do here on earth, God will confirm in heaven, just as the master ratifies the decision of his servants. Did He not give them all the powers of heaven? – Saint John Chrysostom (
d. 407)
Just as in the Old Testament the priest makes the leper clean or unclean, so in the New Testament the bishop and presbyter [i.e. priest] binds or looses not those who are innocent or guilty, but by reason of their office, when they have heard various kinds of sins, they know who is to be bound and who loosed. – Saint Jerome (
d. 420)
