Okay, so this apparently ties in with Christ's crucifixion on a Friday and it's still in effect, as I understand it. Do you Catholics (Victor, Athanasius, Scott, FGS, etc.)abstain from meat on Fridays? Why or why not?
It is actually one of two fasts mentioned very early on, the other is Wednesday, in memory of the betrayal. Western and eastern fasting practices started to diverge quite early on, with Wednesday losing importance in the west pre-Schism, I believe. We still keep both fasts, though.
I'm not sure exactly when Rome started allowing fish (it may have been pre-Schism but if so it was only within the See of Rome) but it certainly is not the original fasting rule of the Church, which was based, as you'd expect, on an eastern Mediterranean diet. All meat, dairy products, fish, alcohol and olive oil were forbidden. The only non-vegetarian produce that was allowed was shellfish. With minor regional variations (usually down to certain climates not being conducive to such practices) we still follow this.
I believe the curent level of fasting in the RCC (which is certainly far, far less than in my grandmother's time) came about at roughly the time of the Vatican II reforms. I'm sure an RC would be able to give you more accurate information. I just wanted to give some background on the fasts from when our churches were one (or shortly thereafter).
