1Co 15:6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
1Co 15:7 After that, he was seen of James; then of all the apostles.
1Co 15:8 And last of all he was seen of me also, as of one born out of due time.
And we decline/reject your so called Tradition because the scriptures alone contradict it so often...Scripture says Paul saw Jesus...
So Paul was failing as an evangelist and Peter had to rescue him??? Where is a face palm picture when I need one???
So when did this 'tradition' start??? And who passed it on to your religion??? Which one of the earliest church fathers wrote about it???
I guess so.
The four witnesses are
Clement of Rome (50-60 A.D.),
Ignatius of Antioch (Bishop of Antioch from 70-108 A.D., then taken to Rome for martyrdom),
Justin Martyr (100-165 A.D.) and
Irenaeus of Lyons (around 202 A.D.).
The answers to your questions are there. I'm no apologist, truly, and just quote early Church fathers.
There is SO much to learn about the early Church, those first few hundred years after Christ when there WAS no "New Testament" but only scattered scroll collections of gospels and epistles. Most people couldn't read anyway and few, if any, could afford to buy a real book. Only the wealthy could, as I have read.
So those first early Church fathers HAD to have traditions for people to follow. They traveled the known world.
Sidenote: My husband and I visited Turkey in 2008. There were enormous amounts of underground "churches" where the first Christians were forced to worship. They were tanatmount to underground cities. I didn't like seeing them--WAY, WAY too sad and depressing. The early Church was persecuted for several hundred years but...persisted, thanks to the early church fathers who traveled and preached all over the known world, no books, only words and their own Christian (Read that as Catholic) deeds.
