According to scripture, private interpretation of the Bible is not condoned. (2 Peter 1:20). For that reason, Christ gave us the Church.
What Church? Scripture reveals this Church to be the one Jesus Christ built upon the rock of Saint Peter (Matt. 16:18). By giving Peter the keys of authority (Matt. 16:19), Jesus appointed Peter as the chief steward over His earthly kingdom (cf. Isaiah. 22:19-22). Jesus also charged Peter to be the source of strength for the rest of the apostles (Luke 22:32) and the earthly shepherd of Jesus' flock (John 21:15-17). Jesus further gave Peter, and the apostles and elders in union with him, the power to bind and loose in heaven what they bound and loosed on earth. (Matt. 16:19; 18:18). This teaching authority did not die with Peter and the apostles, but was transferred to future bishops through the laying on of hands (e.g., Acts 1:20; 6:6; 13:3; 8:18; 9:17; 1 Tim. 4:14; 5:22; 2 Tim. 1:6).
By virtue of this divinely-appointed authority, the Catholic Church determined the canon of Scripture (what books belong in the Bible) at the end of the fourth century. We therefore believe in the Scriptures on the authority of the Catholic Church. Nothing in Scripture tells us what Scriptures are inspired, what books belong in the Bible, or that Scripture is the final authority on questions concerning the Christian faith. Instead, the Bible says that the Church, not the Scriptures, is the pinnacle and foundation of the truth (1 Tim. 3:15) and the final arbiter on questions of the Christian faith (Matt. 18:17). It is through the teaching authority and Apostolic Tradition (2 Thess. 2:15; 3:6; 1 Cor. 11:2) of this Church, who is guided by the Holy Spirit (John 14:16,26; 16:13), that we know of the divine inspiration of the Scriptures, and the manifold wisdom of God. (cf. Ephesians 3:10).
You didn’t really answer my question at all. Why are we commanded to study Scripture, when, according to you, we are unable to fathom it? Remember, you said that if we could interpret it correctly, then nobody would misinterpret it, so according to you, we can’t figure it out. So, why not just command us to listen to the church instead, and not bother with Scripture?
I wouldn’t command my children to study some high-level post graduate work which they couldn’t hope to understand, so why should I believe that God would engage in similar foolishness?
