His contribution to theology is a quibble.

The old dogmas are to stand: only the language is to be adjusted to the modern intelligence.

You may picture him with drawn sword--a sword tempered in inquisitorial fires--standing guard over his quibble and ready to defend it with his spiritual life.
His opinions are apt to place him among minorities.

He was against the War, and during that long-drawn agony attracted to himself the mild attention of the authorities.

I believe he likened the great struggle to a battle between Sodom and Gomorrah.
