'Christian Ethics and the Animal Kingdom' by the Duchess of Hamilton

Here's a theological treatise from 1935 which I stumbled upon only recently and some striking excerpts from the author's moral case.

'Christianity and Vegetarianism' by Esme Wynne-Tyson

From The Vegetarian News (Spring 1956) See also: 'The Saviour of the World'

Quotation: H.W. Hales (1957)

"I believe that vegetarianism is a privileged and enlightened way of life. Let us then be tolerant with those less fortunate in spiritual understanding. We look forward with confidence and longing for the Bible's promised VEGETARIAN NEW EARTH. This will fully justify and condone our inspired way of life on this earth." From a letter, headed 'Christians and Animal Welfare' which was published in The Vegetarian News (Winter 1957 edition)
