St. John of Kronstadt-Oneness

"As the Holy Trinity, our God is One Being, although Three Persons, so, likewise, we ourselves must be one. As our God is indivisible, we also must be indivisible, as though we were one man, one mind, one will, one heart, one goodness, without the smallest admixture of malice - in a word, one pure love, as God is Love. "That they may be one, even as We are One" (John 17:22).
