I want to know how a YEARLY reminder of God's saving power (Passover) managed to morph into COMMUNION: something that occurs every time the church doors are open.

Ever read the Book of Acts?
Acts 2:41-47
41Those who accepted his message were baptized, and about three thousand were added to their number that day. 42****They devoted themselves to the apostles’ teaching and to the fellowship, to the breaking of bread and to prayer.**** 43Everyone was filled with awe, and many wonders and miraculous signs were done by the apostles. 44All the believers were together and had everything in common. 45Selling their possessions and goods, they gave to anyone as he had need. ****46Every day they continued to meet together in the temple courts. They broke bread in their homes and ate together with glad and sincere hearts,**** 47praising God and enjoying the favor of all the people. And the Lord added to their number daily those who were being saved.
Apparently, FROM THE BEGINNING, early Christians were receiving the Eucharist often. They DEVOTED THEMSELVES TO IT.
