Matthew 9:11 And when the Pharisees saw this, they said to his disciples, “Why does your teacher eat with tax collectors and sinners?”
The Pharisees should have understood the meaning of sharing a meal together but their teachings failed them due to critical judgement.
Luke 22:19-20 English Standard Version
19 And he took bread, and when he had given thanks, he broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.” 20 And likewise the cup after they had eaten, saying, “This cup that is poured out for you is the new covenant in my blood.
The sharing of food and drink is a sign that a covenant has been made. The Pharisees just did not get it.
Exodus 24:7-8 English Standard Version
7 Then he took the Book of the Covenant and read it in the hearing of the people. And they said, “All that the Lord has spoken we will do, and we will be obedient.” 8 And Moses took the blood and threw it on the people and said, “Behold the blood of the covenant that the Lord has made with you in accordance with all these words.”
Perhaps they only concerned themself about getting what was rightly theirs.
As described in Leviticus 3, a Peace Offering could consist of male or female cattle, sheep, goats, or bread. In some cases, the breast or thigh would be offered to the high priest and the rest was to be eaten by the assembled parties. The rest of the portions were burned after two days as an offering to God— symbolizing a shared meal. Source: Alabasterco.com
When we only concern ourselves with getting everything we think we deserve, we ignore the covenant promises and fail to honor God who made these covenants to begin with. The sharing of the meal is supposed to be a symbol of our faith in the One who has blessed us and saved us.
John 17:17-22 English Standard Version
17 Sanctify them in the truth; your word is truth. 18 As you sent me into the world, so I have sent them into the world. 19 And for their sake I consecrate myself, that they also may be sanctified in truth. 20 “I do not ask for these only, but also for those who will believe in me through their word, 21 that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me. 22 The glory that you have given me I have given to them, that they may be one even as we are one,
A blessing to us through the Word because we believe in Him who made the New Covenant.
