Rituals do NOT save anyone! They never have and they never will.
I KNOW what Communion is HOWEVER it is NOT a requirement to be saved. Christ clarified that on the cross. He told the thief next to him, he would be with Him in paradise. Thief was NOT baptized, nor did he have communion. So unless Christ is a liar(unlikely) this should clarify that Communion is NOT a requirement for eternal life.
Go ahead and refuse to do what Jesus commanded all men to do. See if I care, but you will, in the grisly end.
