I want to add something to all of this.
The partaking, this has helped me understand and prove that Jesus was not meaning to only the anotined. Straight from the Bible:
Starting at John 6:1-14 where Jesus is feeding the 5 thousand we see a large group of people (5,000 plus the disciples). In verse 15 Jesus withdrew until evening. After this the disciples were crossing the sea in and Jesus followed by walking on the water (verses 16-21).
This part is pretty simple and basic, but when we get to verse 22 thru 24 we see that the large group were still trying to follow Jesus. They find Him at verse 25. Now this group was said to be 5 thousand, but we can gather that not all of them went.
In verse 25, the growd asked Jesus " When did you get here?" Jesus goes on to answer them and talk with them. Jesus speaks about the bread they ate, and what "works" are works of God. Jesus continues to tell them of this bread in verse 32 that comes down from Heaven and how God provided for Moses and the Israelites. Then they said in verse 34"give us this bread". Jesus said He was this bread in verse35.
So who is asking for this bread? The crowd that were fed. This is a large group and were they baptized? Anointed? I think not, they were still learning from Jesus and seeking.
After Jesus told the crowd that He was the bread, the Jews heard of this and were grumbling (verse 41). They could not grasp how Jesus could be from heaven. They did not believe. They were not anointed. They were not baptized either. But Jesus spoke to them and told them about who He was and that He is the bread of life. Then the Jews began to argue (verse 52), and then this is where Jesus said verse 53 "...unless you eat the flesh of the Son of Man and drink His blood, you hvae no life in yourselves."
So who did Jesus tell this to?
Read it, not from what I wrtoe here, but in the Bible itself. See for yourself who He was talking to.
I hope this helps.
