Read Psalm 119.
Why is God’s word not sufficient for you?
God’s Word doesn’t instruct that it’s sufficient. If God’s Word was sufficient, Our Lord would not have sent the Apostles out to preach. He would have ordered them to sit down and start writing the Gospels, and then hand out texts. Since the Gospels were not written for several decades after the death and Resurrection of Our Lord, anyone who declaims oral tradition needs to first demonstrate why Jesus left a Church without any New Testament with which to convey His Word, and why He would deprive anyone of the sole deposit of faith for roughly forty to fifty years.
As I stated, Sola Scriptura demands that matters of faith depend only on Scripture, yet Sola Scriptura is a concoction of Protestant traditon, not anything based in the Scripture it gives sole power to. If there’s no proof in Scripture that Scripture alone is efficacious, on what basis do you believe the doctrine of Sola Scriptura?
With regard to “vain repetition”, I recommend reading Psalm 136, and see if you can identify any repetition.
I also recommend Revelation 4:8:
“And the four living creatures, each of them with six wings, are full of eyes all round and within, and day and night they never cease to sing, “Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!”
Are the angels defying Christ? That would make them demons.
So what’s the definition of “repetition” vs. Jesus’ words “VAIN repetition”?
The definition of “vain” is as follows:
“Characteristic of false pride; having an exaggerated sense of self-importance”
Jesus’ specifically condemned VAIN repetition, not “repetition” itself. Since you place the utmost importance in every word of Scripture, I find it puzzling that you ignore this adjective for the sake of condeming any kind of repetition whatsoever. The Lord made clear that vanity in prayer is a sin - i.e., the Pharisees on the street corner vs. praying in your room where only God sees you. Thus, repetitive prayer designed to draw attention to oneself instead of to God is worthy of condemnation, but to extend this to all repetitive prayer is not exegetically sound, since the angels contradict this very command.
