I’ve typed up a long quote that I really like. The parts best liked are bolded.

Let us now discover more specifically how he [man] is the image and likeness of God and what is the standard or criterion by which he can be measured and estimated. This standard can be no other than the divine virtures which are revealed in him. Therefore, every man imbued with divine qualities, who reflects heavenly moralities and perfections, who is the expression of ideal and praiseworthy attributes, is, verily in the image and likeness of God. If man possesses wealth, can we call him an image and likeness of God? Or is human honor an notoriety the criterion of divine nearness? Can we apply the test of racial color and say that man of a certain hue — white, black, brown, yellow, red — is the true image of his Creator? We must conclude that color is not the standard and estimate of judgement and that it is of no importance, for color is accidental in nature. The spirit and intelligence of man is essential, and that is the manifestation of divine virtues, the merciful bestowals of God, the eternal life and baptism through the Holy Spirit. Therefore, be it known that color or race is of no importance. He who is the image and likeness of God, who is the manifestation of the bestowals of God, is acceptable at the threshold of God — whether his color be white, black, or brown; it matters not. Man is not man simply because of bodily attributes. The standard of divine measure and judgement is his intelligence and spirit.
