“I do not claim any ability to read God's mind. I am sure of only one thing. When we look at the glory of stars and galaxies in the sky and the glory of forests and flowers in the living world around us, it is evident that God loves diversity. Perhaps the universe is constructed according to a principle of maximum diversity.”

"Belief and Creativity" Address in Hamburg (11 April 1980); as quoted in Moving Target https://books.google.com.mx/books?id=2SwUAAAAQBAJ&source=gbs_navlinks_s (2013), Faber & Faber
Context: Reason, when it is refined into logic, has something to offer but only in terms of itself and depends for its effect and use on the nature of the premise. That useful argument as to how many angels can stand on the point of a needle would turn into nothing without the concept of angels. I took a further step into my new world. I formulated what I had felt against a mass of reasonable evidence and saw that to explain the near infinite mysteries of life by scholastic Darwinism, by the doctrine of natural selection, was like looking at a sunset and saying "Someone has struck a match". As for Freud, the reductionism of his system made me remember the refrain out of Marianna in Moated Grande — "He cometh not, she said, she said I am aweary aweary, O God that I were dead!". This was my mind, not his, and I had a right to it....
We question free will, doubt it, dismiss it, experience it. We declare our own triviality on a small speck of dirt circling a small star at the rim of one countless galaxies and ignore the heroic insolence of the declaration. We have diminished the world of God and man in a universe ablaze with all the glories that contradict that diminution.
Of man and God. We have come to it, have we not? I believe in God; and you may think to yourselves — here is a man who has left a procession and gone off by himself only to end with another gasfilled image he towns round with him at the end of the rope. You would be right of course. I suffer those varying levels or intensities of belief which are, it seems, the human condition. Despite the letters I still get from people who believe me to be still alive and who are deceived by the air of confident authority that seems to stand behind that first book, Lord of the Flies, nevertheless like everyone else I have had to rely on memories of moments, bet on what once seemed a certainty but may now be an outsider, remember in faith what I cannot recreate.

Google search of the second sentence, in quotes, yields a trio of 2019 books alone, most (there and in following) attributing it to Kepler—e.g., see Prof Basden's 2019 work, [Foundations and Practice of Research: Adventures with Dooyeweerd's Philosophy, The Complex Activity of Research [§10—4.1 Less-Obvious Pistic Functioning in Research], Advances in Research Methods, Abingdon-on-Thames, UK, Taylor & Francis-Routledge, 1st, 9781138720688, https://www.amazon.com/Foundations-Practice-Research-Adventures-Dooyeweerds/dp/1138720682, February 25, 2020] (page 222).
While most citations of Kepler have been traced back to a translation of an original work, this quotation appears broadly without any such sourcing (e.g., Basden). Where it is sourced, the sources are either spurious (e.g., to the "New World Encyclopedia", a Paragon House/Unification Church product https://www.nytimes.com/1984/04/02/arts/unification-church-is-starting-a-publishing-house.html, wherein it is likewise unsourced), or to such sources as Henry Morris' 1988 creationist work, [Men of Science, Men of God: Great Scientists Who Believed the Bible, Green Forest, AR, Master Books, 21st reprint, 9780890510803, https://www.amazon.com/Men-Science-God-Henry-Morris/dp/0890510806, February 25, 2020] (page 21f).
Until a scholarly source is found that ties these statements to an original text from Kepler, they formally must be considered unattributed to Kepler.

A Cabinet of Jewels

The Sun My Heart (1996)
Context: There is no phenomenon in the universe that does not intimately concern us, from a pebble resting at the bottom of the ocean, to the movement of a galaxy millions of light years away. Walt Whitman said, "I believe a blade of grass is no less than the journey-work of the stars...." These words are not philosophy. They come from the depths of his soul. He also said, "I am large, I contain multitudes." This might be called a meditation on "interfacing endlessly interwoven." All phenomena are interdependent. When we think of a speck of dust, a flower, or a human being, our thinking cannot break loose from the idea of unity, of one, of calculation. We see a line drawn between one and many, one and not one. But if we truly realize the interdependent nature of the dust, the flower, and the human being, we see that unity cannot exist without diversity. Unity and diversity interpenetrate each other freely. Unity is diversity, and diversity is unity. This is the principle of interbeing.

William Boulting, in Giordano Bruno: His Life, Thought, and Martyrdom (1916) online excerpt http://www.class.uidaho.edu/mickelsen/texts/Bruno's%20Eroici.htm
Context: Of Bruno, as of Spinoza, it may be said that he was "God-intoxicated." He felt that the Divine Excellence had its abode in the very heart of Nature and within his own body and spirit. Indwelling in every dewdrop as in the innumerable host of heaven, in the humblest flower and in the mind of man, he found the living spirit of God, setting forth the Divine glory, making the Divine perfection and inspiring with the Divine love.
