"Thus, my covenant shall be in your flesh
as an everlasting pact."

Jesus answered and said to them, "I performed one work and all of you are amazed because of it. Moses gave you circumcision - not that it came from Moses but rather from the patriarchs - and you circumcise a man on the sabbath.

"Stop judging by appearances,
but judge justly."
John 21:24
When they came to Jerusalem, they were welcomed by the church and the apostles and the elders, and they declared all that God had done with them.

Since there is only one God,
who will justify the circumcised by faith
and the uncircumcised through that same faith.
