and you have also forgotten 2 Peter 1:20-21
20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
true Christianity is described in the Bible... and what i know concerning Eastern Orthodoxy, it is virtually identical to Roman Catholicism, with the exception that you follow patriarchs instead of the Roman Pope
Roman Catholicism is not virtually identical to Roman Catholicism. It is Protestantism that is virtually identical to Roman Catholicism. Both Catholicism and Protestantism believe in spiritual individualism: self-authority, private interpretation. Orthodoxy believes in Church Tradition, the Tradition of God and the Holy Apostles, the Work and Presence of the All-Holy Spirit in the Church, and the Communion of Saints of the Church Fathers and 7 Church Councils and the One Church Faith (Jude 3) delivered to all the Church Saints.
True Christianity is described in the Orthodox Church: the Church tells what the Bible means (Acts 8:30-31).
The Catholics believe in the Vicar of Christ, the Pope, a substitute for the absent Holy Spirit, and they believe in the Virgin Mary as a virtual goddess, another substitute for the absent Holy Spirit. The Holy Spirit is absent from Catholics because of the Filioque heresy. The Holy Spirit is also absent from Protestants because of the Filioque heresy; He is absent because of their Bible idolatry, they substitute a Book, the Bible, for Christ.
Eastern Orthodoxy is based on the Holy Spirit and the Community of Christ: The Spirit and the Bride.
The Church, The Body of Christ. Only Orthodoxy is the Truth.
Catholicism and Protestantism are man-made heresies.
So is Oriental Orthodoxy.
