Yes, yet again we have more puzzling and confusing instructions given by the Christ to his disciples. I am referring to what has been called "The Great Commission". Simpy put it is an instruction by the Christ to his disciples to go out into the world and make more disciples.
"Make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit" (Matthew 28:19). https://www.biblegateway.com/passage/?search=Matthew+28%3A19&version=NIV
But if we back up a little in the same gospel we can read that this instruction is not as inclusive as it appears later:
"These twelve Jesus sent out with the following instructions: “Do not go among the Gentiles or enter any town of the Samaritans. Go rather to the lost sheep of Israel.” (Matthew 10:5–6).
This was not then the universal message that appears at Matthew 28:19 but an instruction to go to the "lost sheep of Israel" only. i.e. Jews and not all Jews either it appears the Samaritans - Israelite descendants were off the guest list too.
It appears too that this - not so - inclusive instruction doesn't apply to all the people of "all nations" either, when we read the words from the lips of the Christ himself and his encounter with the Canaanite woman:
Jesus rejected her plea to heal her daughter, saying; “I was sent only to the lost sheep of Israel.”
The woman came and knelt before him and begged and pleaded. “Lord, help me!” she said.
He replied, “It is not right to take the children’s bread and toss it to the dogs.” (Matthew 15:24–6).
Canaanites are included in a list of nations to exterminate on the instructions of god in the book of Joshua
And staying with the Old Testament, we don’t find an all-inclusive message there, either.
No Ammonite or Moabite or any of their descendants may enter the assembly of the lord, not even in the tenth generation (Deuteronomy 23:3).
And god also forbids intermarriage with these foreign tribes (Deut. 7:3; Ezra 9:2, 10:10; Nehemiah 13).
So what is to be made of this "Make disciples of all the nations, from (Matthew 28:19).
