All denominations and people get something wrong theologically. Obviously, some get it more wrong than others and some get it so wrong that their eternal destiny is in hell.
The critical crux of the matter is: What is/are the source(s) of God instructions to man. You can exercise your beliefs perfectly according to the source you follow, but if the source is faulty, then you are treading through a mine field that could lead to eternal death.
The Eucharist
When it comes to the Eucharist, which most Protestants call ‘The Lord’s Supper,” or “Communion,” the Roman Catholic Church holds to the doctrine of
transubstantiation—the idea that the edible ritual elements used during the mass literally become the body and blood of Christ. Is this worship or idolatry?
The Magisterium
This body also allows the church to make official pronouncements on contemporary issues which Scripture might not directly address. Are they speaking for God or man?
Tradition
“…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.” If the R.C.s are correct, then the protestants are ignoring God.
Justification
“What the Roman Catholic rejects is that there is an imputed righteousness of Christ to us at the moment of salvation, that we are counted as fully righteous in the sight of God”. Works salvation? Gal. 5:2 ?
Priesthood of All Believers
That which was reserved just for the magisterium, the ability to bind and loose to forgive and withhold forgiveness through the sacraments and through penance and such, that was just the role of the priest. From Luther on, we have the ability to confess our sins to one another, pronounce forgiveness as the scripture says.” Man can pronounce forgiveness?
Veneration of the Saints and the Virgin Mary
Roman Catholics see veneration, not as praying
to the Saints and the Virgin Mary, but as praying
through them. This is seen as similar to asking a brother or sister in Christ to pray for you. Dr. Svigel adds that departed saints are also “able to spill over their overabundance of grace to us.”
Furthermore, Dr. Horrell notes that the Virgin Mary is seen as “the mother of our Lord, and therefore she is the mother of his body, and his body is the church, so she is the mother of the church. He is the creator of all things. So she is the mother of angels. She is the mother of humanity, as is sometimes said.”
