I want to pick up on your comment that what Christians believed from the very beginning.
What Christians PRACTISED from the very beginning was the agape meal. In Acts it says they met daily for fellowship, teaching prayer and breaking of bread. Bread here means a raised loaf.
In New Testament times, when you had a meal together, the head of the house took a loaf of bread and broke it into pieces and gave each person a piece. Until this happened the meal did not start.
In Corinthians, Paul was giving instructions on how to conduct themselves during that meal. Some people were bringing food and eating it which meant those coming later had none. He said if you are hungry eat at home first. Now if they were hungry, do you really think that a wafer and a sip of wine would satisfy that hunger?
Of course not. This meal was all about food, which they shared together as the body of Christ.
The wafer and sip of wine and all the mumbo jumbo and regalia that goes with it was the product of an apostate church that had lost its way.
And please don't refer to Jesus and the last supper to justify your rituals. The last supper was a meal, not affirmation to introduce a religious ritual. FYI, when Jesus said do this in remembrance of me, which by the way is only recorded in one book (Luke) do this means do this now. It does not mean keep on doing it.
Sorry if I have burst your bubble but them's the facts.
