I am ignorant of the specific cultural factors that led to dissipation in connection with the Sacrament of the Altar as practiced in Corinth, but the town, as I understand it, had a penchant for partying. We would be susceptible to the same except as the First Petition of the Our Father is answered in our midst, and it is, albeit in places the world does not count as much.
For the Church at Corinth, the Apostle Paul was given to call them to repentance and to iterate most clearly that one should not partake of the Body and Blood of Christ Jesus without discernment. It is for our comfort that Christ Jesus established this Sacrament, so that His salvific benefits may be imbibed by poor sinners to strengthen them in faith and love as we await the Day when we shall see Him as He is.
My priest has talked about this.
After funerals at my church, we have a reception.
I guess at their partying (which was before the Home Mass, BTW,) some people brough (and possbily hoarded) rich and elegant foods and wine, while the poorer people only brought bread (if that).
Yes, they discontinued it.
Evidently the Corintians were so far out that St. Paul wrote them a second letter, which was so torrid that it was never circulated. In other words, he really bawled them out.
