Augustine of Hippo
He speaks highly of the spiritual circumcision of the heart, which denotes a will that is free from all illicit desires. This is not according to the letter, which instructs and admonishes, but rather according to the Spirit, which provides assistance and restoration. Consequently, the commendation of such individuals comes not from humanity, but from God, who, by His grace, has bestowed upon them what they are recognized for. It is declared, “By the Lord shall my soul boast” (Ps 33:3), and similarly, “From Thee shall my praise be.” They do not offer praise to God for their humanity or seek validation for their own righteousness.
I do not seek My own glory, for You are My glory, You who reside in the holy place; and all praise belongs to Israel, as You now hear the Holy One imploring You. In the universal Church, I acknowledge You. Throughout the entire world, I profess You. I will present My commitments before those who revere Him. I will offer the sacred elements of My Body and Blood in the sight of those who honor Him.
