A good example of what you are looking for are the works of Anselm of Canterbury such as his Monologion and Why God Became Man. You can see his relance on "the constraints of reason" and "everyday arguments" in these works. He makes sure that "nothing whatsoever [is] to be argued on the basis of the authority of Scripture". Usually he starts with Platonic assumtions such as ideas are more real than sense objects. Then he reasons using logic and arguments to Christian conclusions.
