I can see that your mind is made up and not willing to accept the reason, logic, faith and teachings of the Catholic Church, but I caution you not to make false statments about the teachings of the Catholic Church (for your sake).
St. Thomas (II-II:11:1) defines heresy: “a species of infidelity in men who, having professed the faith of Christ, corrupt its dogmas”. “The right Christian faith consists in giving one’s voluntary assent to Christ in all that truly belongs to His teaching. There are, therefore, two ways of deviating from Christianity: the one by refusing to believe in Christ Himself, which is the way of infidelity, common to Pagans and Jews; the other by restricting belief to certain points of Christ’s doctrine selected and fashioned at pleasure, which is the way of heretics. The subject-matter of both faith and heresy is, therefore, the deposit of the faith, that is, the sum total of truths revealed in Scripture and Tradition as proposed to our belief by the Church. The believer accepts the whole deposit as proposed by the Church; the heretic accepts only such parts of it as commend themselves to his own approval. The heretical tenets may be ignorance of the true creed, erroneous judgment, imperfect apprehension and comprehension of dogmas: in none of these does the will play an appreciable part, wherefore one of the necessary conditions of sinfulness—free choice—is wanting and such heresy is merely objective, or material. On the other hand the will may freely incline the intellect to adhere to tenets declared false by the Divine teaching authority of the Church. The impelling motives are many: intellectual pride or exaggerated reliance on one’s own insight; the illusions of religious zeal; the allurements of political or ecclesiastical power; the ties of material interests and personal status; and perhaps others more dishonourable. Heresy thus willed is imputable to the subject and carries with it a varying degree of guilt; it is called formal, because to the material error it adds the informative element of “freely willed”.
I hope you continue to seek and find the TRUTH.
PAX VOBISCUM
Heresy is what Jesus said it is: “teaching for doctrines the commandments of men” (Mat 15:9). The doctrine of forbidding communion is heresy. I care not for the warnings from man's authority, but I hope you heed the warnings from God's authority in Scripture, previously cited for your convenience and, hopefully, study.
There is no logic or reason to the Catholic church's teachings that are outside Scripture, nor is there any Scriptural support for them.
Therefore, as Christian, we are obligated to warn people when we see false teaching passed off as truth.
Your threats will not intimidate anyone into silence.
