[A.J.Armitage]

It boils down to this: you have faith in Abraham, and in his claim to have been told that circumcision was some sort of bizzarre divine covenant. I do not.

I have faith in the testimony of Christ and His servants.

Jesus testified that the Scriptures -- of which the Torah (including Genesis 17) was the preeminent part -- cannot be broken.

Jesus testified that Abraham will be in Heaven.

Paul testified that Abraham was righteous because of his faith.

The author of Hebrews testifies to the same thing, and singles out Abraham's willingness to offer up Isaac.

Do you believe them, or not?
