Who told you that a wafer and wine gives eternal life?
I do recall a certain man saying that if you don’t ‘eat my flesh and drink my blood, there is no life in you. He also said some very hard to understand, nuanced words like “this is my body” does that mean it’s a wafer? Same goes for the wine.
At the last supper he told his disciples that he would no more drink of this fruit of the vine till he would drink it new with them in heaven. How plain is that? Or do you think the Lord and his disciples are going to drink his blood in heaven?
In the book of Acts we see numerous cases of souls converted. Some are detailed, for example, the Samaritans, in chapter 8.
We read of them hearing the gospel from Philip.
We read of miracles from God by Philip.
We read of their having great joy.
We read of many of them being baptized in the name of the Lord Jesus.
We read of them being given the gift of the Holy Ghost after the laying on of hands by Peter and John.
We read of Simon the sorcerer being so amazed at witnessing the people being filled with the Spirit, that he offered money for the power to give people the Holy Ghost.
Did he offer money after seeing Philip cast out unclean spirits? No.
Did he offer money after seeing Philip heal many that had palsied? No.
Did he offer money after seeing many get baptized in the name of Jesus? No, but he saw his need to be baptized as well.
But when he saw the people receive the Holy Ghost, he was amazed. Do you think he offered money for the ability to lay hands on people, tell them to repeat after him and recite the sinners pray, and say that they received the Lord as their personal savior?
In that whole story, there is no mention of the Lord’s supper.
There are accounts in Acts of the church members breaking bread together, but no mention of the wine, or other details.
Peter gives the conversion instructions in Acts 2:38. The Lord had ascended and left his disciples in charge of remitting sins. And remit sins they did, in obedience to the Lord’s commissions, found in Matt. 28:19,20; Mark 16:15-18; Luke 24:46-49; and John 20:21-23.
