He did say go and sin no more.
However some churches (mostly flying a rainbow flag) preach “go and sin some more”.
I am just saying, Jesus didn’t say ONLY the sinless should do this in his memory.
And for the church to say only those without sin can receive communion is a rule that Jesus didn’t make.
There are many others, I am a bit cynical about the church and what they will let people do if paid the right amount of money.
