St. Peter teaches the Church to, "Be of one mind." What an important reality we are being taught. For each living stone in Christ's Church to be of one mind is to exist like the Holy Trinity. Father, Son, and Holy Spirit are three Persons yet One. How are they One? The exist in the bonds of absolute love, unity, and harmony of the will. So the Church is called to be of one mind with one another and with our God. Our God is glorified in the wonder of Christian unity.
