Because you have added to it with the traditions of men and MOPIOS, Magisterium’s own interpretation of scripture. THEY EXPECT YOU TO BLINDLY FOLLOW WHERE THEY LEAD.
I recognize again the practice of not letting the 8th Commandment get in the way of a good anti-Catholic smear. You should be as concerned at what some have left out as what you thing the Catholics have added. Intellectual honesty requires that you make an effort to address your ignorance before you proclaim.
Every Protestant poster in these threads claims the right to individually interpret scripture or choose whose interpretation (Calvin, Luther, Rev. Billy-Bob Rolex, etc.) but denies this right to Catholics. Catholics hold that the same Apostolic Tradition that established canon and brought the written portion of the Revealed Word also continues through Tradition by that right denied to us by Protestants.
"Sacred Scripture is the speech of God as it is put down in writing under the breath of the Holy Spirit."
"And Sacred Tradition transmits in its entirety the Word of God which has been entrusted to the apostles by Christ the Lord and the Holy Spirit. It transmits it to the successors of the apostles so that, enlightened by the Spirit of truth, they may faithfully preserve, expound and spread it abroad by their preaching."
As a result the Church, to whom the transmission and interpretation of Revelation is entrusted, "does not derive her certainty about all revealed truths from the holy Scriptures alone. Both Scripture and Tradition must be accepted and honored with equal sentiments of devotion and reverence."
"THEY EXPECT YOU TO BLINDLY FOLLOW WHERE THEY LEAD."
This is the most ignorant of your proclamations. Unlike those who teach predestination and the Solas, the Catholic Church teaches that God created man a rational being, conferring on him the dignity of a person who can initiate and control his own actions. "God willed that man should be 'left in the hand of his own counsel,' so that he might of his own accord seek his Creator and freely attain his full and blessed perfection by cleaving to him. Man is rational and therefore like God; he is created with free will and is master over his acts.
"God willed that man should be left in the hand of his own counsel (cf. Sir 15:14), so that he might of his own accord seek his creator and freely attain his full and blessed perfection by cleaving to him"
Freedom is the power to act or not to act, and so to perform deliberate acts of one's own. Freedom attains perfection in its acts when directed toward God, the sovereign Good.
Freedom characterizes properly human acts. It makes the human being responsible for acts of which he is the voluntary agent. His deliberate acts properly belong to him.
The imputability or responsibility for an action can be diminished or nullified by ignorance, duress, fear, and other psychological or social factors.
The right to the exercise of freedom, especially in religious and moral matters, is an inalienable requirement of the dignity of man. But the exercise of freedom does not entail the putative right to say or do anything.
"For freedom Christ has set us free" (Gal 5:1).
