2 Timothy 3:New King James Version (NKJV)
10 But you have carefully followed my doctrine, manner of life, purpose, faith, longsuffering, love, perseverance, 11 persecutions, afflictions, which happened to me at Antioch, at Iconium, at Lystra—what persecutions I endured. And out of them all the Lord delivered me. 12 Yes, and all who desire to live godly in Christ Jesus will suffer persecution. 13 But evil men and impostors will grow worse and worse, deceiving and being deceived. 14 But you must continue in the things which you have learned and been assured of, knowing from whom you have learned them, 15 and that from childhood you have known the Holy Scriptures, which are able to make you wise for salvation through faith which is in Christ Jesus.
16 All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, 17 that the man of God may be complete, thoroughly equipped for every good work.
2 Timothy 4 New King James Version (NKJV)
4 I charge you therefore before God and the Lord Jesus Christ, who will judge the living and the dead at His appearing and His kingdom: 2 Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching. 3 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; 4 and they will turn their ears away from the truth, and be turned aside to fables. 5 But you be watchful in all things, endure afflictions, do the work of an evangelist, fulfill your ministry.
The apostle Paul was clearly convinced of Scriptures.
That all Catholics are, along with St. Paul. But where does the Holy Scripture say that it is the complete rule of faith? I can show you where it says that the Church is the complete rule of faith.
And which OT writings materially provided for further conflative and complimentary writings being discerned and added to the body of wholly inspired writings, as were wholly inspired ones before it, without an infallible magisterium. But which purported infallible Romish teaching are not ( wholly inspired of God), regardless of RC assertions.
And it is Scripture which, as written, manifestly became the transcendent supreme standard for obedience and testing and establishing truth claims as the wholly Divinely inspired and assured, Word of God.
Without which the church would have no foundation, and to which authority it is to be subservient. The church established its Truth claims upon scriptural substantiation in word and in power, following Christ who did so. (Mt. 22:23-45; Lk. 24:27,44; Jn. 5:36,39; Acts 2:14-35; 4:33; 5:12; 15:6-21;17:2,11; 18:28; 28:23; Rm. 15:19; 2Cor. 12:12, etc.) And which testifies (Lk. 24:27,44, etc.) Even though both men and writings of God are so regardless of what men think.
Some RCs have been shown these Truths time and time again, yet continue to waste time by having us engage their sophistry again and again.
