But that’s not Catholic doctrine. The Church accepts the Old Testament as valid and as necessary as the New Testament.
I accept that for the purpose of evangelism, the evangelist must be able to answer questions concerning Our Lord’s OT references. Thus for that purpose, the OT is necessary.
If you are about to say that ALL Christians should be prepared to be evangelists, then, of course your claim is indeed correct. However, the OT is there as a reference book, not as evangelical text.
Remember, for some 350 years after the Crucifixion, there was no New Testament. But the Church preserved and taught the Old Testament in all those centuries. It is possible for Christianity to thrive without the New Testament, but not without the Old.
No Vern, your History here is wrong. The Pauline epistles can be dated to around AD 60, and Gospels, at least in the form of Story Tellers’ traditions existed as early as AD 170, tor Tatian witnessed these tales,as witnessed by Ephrem Syrus.
Yes there was LXX from the beginning, but this was reference material.
If the standard claim is true, what business did St Victor, Bishop of Capua, have in publishing a New Testament Vulgate?
Devotional and evangelical texts have been in circulation since ca AD 60. You might not want to call these texts NT scripture, but they certainly were what became accepted as that.
So we seem to have two classes of scripture:
1/ Devotional and evangelical texts, which comprise almost exclusively NT scripture, and
2/ Reference texts, which comprise almost exclusively OT scripture.
For a simple Christian, who for the cares of this life, is never going to be an evangelist, but will struggle, just to follow Our Lord’s commands of Love, the devotional texts will suffice.
For a Christian, determined to share the Gospel, he must be prepared to answer critical claims from the Gospels, so he must have, and be familiar with the reference material.
In this sense, then both NT and OT are necessary, but they serve different, but complementary purposes.
