That would be eighty years after the fact and by then many congregations had indeed turned from the truth.
The seven letters of St. Ignatius were written within twenty years (perhaps as few as fifteen) of the death of St. John. Thus this congregationalist style of church that you imagine must have last but a very short time.
Once again you go to the writings of a man rather than the Bible and letters written 80 years after the facr. But you still got that right. Maybe you are starting to see the truth. Just to help you along in your search try reading Gal. 3:1, written in approximately AD49 and also the letters to the seven churches in Rev. Chap.2-3.
Still waiting for you to provide a scripture that says that there must be a Priest involved in order to celebrate the Lord's Supper or are you unable to do so?

I have shown you that our Lord only gave the command to the apostles and not to all his disciples. I am still waiting for you to provide Scripture that says any Christian believer can celebrate the Lord's Supper or are you unable to do so?
