Ever hear of Campus Crusade for Christ? Bill Bright, its founder, was Presbyterian.
Ever hear of Evangalism Explosion? D. James Kennedy, its founder, is Presbyterian.
Ever hear of the Jesus film? Financed by a presbyterian, and distributed by Campus Crusade.
You mean to tell me the founder of the organization that created the 'Four spiritual laws" booklet that is so condemned by many members of the GRPL is was a Calvinist? Being, or having been, a member of a Presbyterian church is hardly evidence that one is a Calvinist. I was once a member of the CRC, and I would hardly be classified as a Calvinist; nor an Arminian, for that matter.
