Eating Human Flesh?

This is being taken completely out of context. If you look at the rest of the surrounding verses, you would see that Jesus is actually talking about communion, in which you eat the bread representing Jesus' body, which was broken for us, and the wine representing His blood, which He spilled for us.

In other words, it's a metaphor, not to be taken seriously

In other words, you can use a metaphor of sin and it not be sin?

[Mat 5:28 KJV] 28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.

You look on a woman with lust and it's literal adultery?

but you say the wine is blood, and it's not a sin?

What's the NT standard? it's so confusing.

Thank Yah I know my redeemer.

[Isa 43:3 KJV] 3 For I [am] Yehowah thy God, the Holy One of Israel, thy Saviour: I gave Egypt [for] thy ransom, Ethiopia and Seba for thee.

Yehowah is our one and only savior and sin is action, not thoughts.

And Yah wouldn't use "communion" which is literally satanic, as David warns of as well:

[Psa 16:4 KJV] 4 Their sorrows shall be multiplied [that] hasten [after] another [god]: their drink offerings of blood will I not offer, nor take up their names into my lips.

Really think on this. Yah forbids drinking blood - he wouldn't use that to form a covenant.

God Bless you.

You do not know anything about this subject, do you?
Read Matthew 26:17–29. That is the story about the Last Supper, which is where this passage is from.
And communion is not the same as a blood offering to a pagan God. It is something we do to remember what Christ did for us. He broke His body and spilled His blood, so in remembrance, we do what He told us to do, which is communion.
He broke the bread, gave it to the disciples to eat, poured the wine and gave it to the disciples to drink, called them His blood and body(as a metaphor) and then told them, "Do this in remembrance of me."
Communion is not the same as drinking blood. It is drinking wine/grape juice to remember that Chirst died for us.
And sin does include thoughts. It can be defined as anything you think, say, or do against God.

1) This is something I know a lot about being a former Christian.

Take away Jesus from it, and it's _EXACTLY_ what pagans do. Look up the act of Theophagy.

2) "It is something we do to remember what Christ did for us."

And I know what this is, but the Torah doesn't permit humans to die for you, and even if he was a valid offering (which he's not and I want to make that clear) the way it was performed also goes against EVERY Torah commandment for offering. Read Lev 17:1-4 - this is for a _VALID_ offering of a Lamb, but performed outside of the gates (like Jesus was sacrificed outside of Jerusalem)

3) Communion is not the same as drinking blood.

I think this depends on what sect of Christianity you are in. Roman Catholics and Eastern Orthodox view it as _exactly_ the same as drinking actual blood. Your view of it goes back at most 200 - 300 years, as even Luther believed it was MORE than remembrance.

4) And sin does include thoughts.

Torah deals with our actions almost exclusively except for coveting. And sin isn't just against God - YHWH most high, who tells us he alone is our savior (Isaiah 43:11) - it is also against other human beings.

This is another serious problem. Ex 23:7

By the death of an innocent or righteous man, the wicked will not be justified.

How are you going to say that the Old Testament doesn't permit anyone to die for you if God actually calls us to acts with sacrificial love. Why is Jesus not a valid offering for all of mankind? He was absolutely perfect and he sacrificed Himself willingly. That's all that is needed to wipe away our sin. The lambs the Israelites sacrificed in the OT were unblemished, just like Jesus. And I do not believe that communion is the same as drinking blood. I don't know how you got the idea that I did, but I am sorry for any confusion I may have caused.
As for sin also being against humans, Jesus said, "What you do to the least of your brothers, you do to Me." So, even if it is against a human, it is also against God.
Also, Exodus 23:7 is talking about the justice system for Israel, not the sacrifice system, as you seem to have taken it.
