He favoured a federation over a total church union. This was highlighted in his 1911 "Alberta Plan", that critiqued the "Union Churches" then being created primarily in Saskatchewan. In 1923, he went on a six-week speaking tour of Eastern Canada for the anti-church union Presbyterian Church Association and became known as "Brown of Red Deer". When the final vote on union was held during late 1924 and early 1925, Brown's Red Deer Presbytery was the sole presbytery in the PCC with a majority vote against Church Union.
