“The vital power of an imaginative work demands a diversity within its unity; and the stronger the diversity the more massive the unity.”

“Unity=diversity in harmony!”

“Peace is not unity in similarity but unity in diversity, in the comparison and conciliation of differences.”

“The bicovenantal structure of the promise and administrative covenants provides the key for understanding the unity and diversity in God's covenantal dealings with men. Unity and continuity are founded on the promise covenants that secure it. The elements of diversity and discontinuity are found in the administrative covenants. But as explained [earlier], the discontinuity [within the administrative covenants] is not theological or ethical, but ceremonial and typological. The law of God, in terms of its ethical demands, does not pass away, nor is it abolished by a new administrative covenant.”

“this is the weakness of most 'edifying' or 'propaganda' literature. There is no diversity...You cannot, in fact, give God His due without giving the devil his due also.”

“The ecological principle of unity in diversity grades into a richly mediated social principle; hence my use of the term social ecology.”

“I take as my guide the hope of a saint: in crucial things, unity-in important things, diversity-in all things, generosity.”
