Reformed View of the Covenant of Grace Destroys Justification by Faith!

Thomas Patient says, "Fifthly, this opinion [believing the covenant of circumcision to be the covenant of grace, aka Reformed view] destroys the doctrine of Justification by faith in Christ, only seeing that it doth hold out another way than by faith, to come to Justification, which is by carnal birth of beleeving parents; for if a soul be admitted into a Covenant of life, I hope you are not ignorant, that Justification is a great privilege in the new covenant, and really the portion of all that are in that covenant."
