"The originator of this new cult was a Mr. William Weir Irvine, a Scotchman,
who went to Ireland about fifty years ago as a preacher in connection with
the Faith Mission. He subsequently left them and started an independent
Mission on his own at a town called Nenagh, Co. Tipperary, where he found
a few hearty people who had recently been converted. These he succeeded
in gathering round himself and they became the nucleus of this new sect."
