From Heppe’s Reformed Dogmatics
Riissen (I, 11): “The use of human reason in theology is (1) to perceive things revealed, Matt. 13:51; (2) to compare them with other things, Acts 17:11; (3) to explain, Neh. 8:8; (4) to distinguish the false; for it is necessary to search out things that differ, Phil. 1:10; (5) to clear it of objections, Rom. 9.
