It seems that many had tried to tell what happened, so Luke felt he needed to research and write down what really happened. Why is it that RCC talks about oral tradition like christians only had the spoken word for 300 years.
The canon was not settled until the late fourth century. The scriptures that exist today have been used since their production,
but not all of them in all places at all times. There was no NT scriptura at all for the first 30 or so years, and the NT was not complete until about 70 years after Christ. We cannot believe that God would leave those early Christians hanging, can we? The oral Apostolic Tradition was the
universal teaching they had, and has endured to this day. It was and is highly revered because the Apostles were eyewitnesses. I don’t think that anyone is complaining that those generatons somehow received deficient instruction because they had no bibles - rather Luke wrote only to
back up what Theophilus had already been orally taught. Acts, by the nature of its content, had to come much later in Church history, as it could not exist until that history was made.
…only that Most scholars agree that Luke was written in the early 60s AD, Luke written before Acts, Acts written before the death of Paul (about 66 AD). Mark the first Gospel, may have been written less than 10 years after Jesus death and Matthew somewhere in between, also possibly within 10 years of the Crucifixion and the Epistle of Jame may be even earlier. Paul’s letters, obviously, written before his death; the epistles of Jon, Peter, Jude, between 60 and 90, with the Gospel of John and Revelations around 90 AD. This means most of what would become the New Testament was written within 35 years of Christ’s ministry.
Careful in following the teaching of scholars who have a vested interest in squeezing the scriptural time frame closer to Christ than they may actually have been. Those who adhere to sola scriptura are especially motivated to shorten that time. My source,
Inside the Bible (excellent resource - have a look) puts it closer to AD 60, based on its content.
However, did Jesus intend for His Church to be scripture alone? Clearly not, since He left no scripture at all, and sent only Apostles forth, rather than scripture. Notice that the Apostles used scripture
in support of their teaching, just as the Catholic Church does to this day. Since scripture is incomplete (
Luke 3:18, John 20:30, John 21:25, Acts 2:40, 1 Corinthians 11:34), it seems also to be an incomplete basis for faith. Theophilus did not have any NT at all, and possibly only Moses and the prophets. Recall also that Jesus opened only the minds of the Apostles to understand scriptures (
Luke 24:45). No such ability is mentioned as applying to average believers - even though we do possess the Holy Spirit. We cannot individually possess the interpretive authority of the Holy Spirit unless Jesus desired division in His Church - as the situation stands today. Since the Word is living, it needs living, breathing Apostles and their successors to further it and correctly interpret it.
These letters were meant to be shared, Peter addressed his letters to Christians is several different regions, and to believers everywhere, Jude to all those chosen by God, James to the 12 tribes scattered around the world, Paul told the Collossians to share their letter with the church in Laodicea, and be sure they read the Laodicean letter. So these leters moved around the first century christian community. Like Henry Jones Sr. said in Indiana Jones and the Last Crusade, “I wrote it down so I wouldn’t have to remember.”
But, not all letters in the NT are considered “catholic”, or universal letters. Neither were all of them shared until the universal Church collected them. Here, you also point out the absolute need for a unified Church with overarching authority. How else would such widely disbursed writings have been shared, preserved and canonized in those days of primitive conditions?
Certainly the letters were shared, but only on the command of the Apostle. I wonder why such a command was necessary, unless they would not have shared the letters. And, recall that the letters carried the weight they did only because of the
living Apostle behind them.
The Catholic Church has never and will never diminish the importance of Sacred Scripture. However, it has and will continue to criticize the exclusion of the Apostolic Tradition (Paradosis) and the teaching authority (Magisterium) that Jesus gave to the Apostles.
I encourage you to entertain the notion that the bible is not, and never was intended as the sole rule of faith - simply because it places the individual ego in charge of interpretation. This has tended to produce the massive, endemic divisions that we see today. Love the Catholic Church or hate her, it remains unified because of the “old man” in charge. And, because of that beloved old man, it is able to resist pressure from the world to change.
