„Anyone who thinks about the great questions of Christian theology soon finds out that a lot of them have already been addressed. It is virtually impossible to do theology as if it had never been done before. There is always an element of looking over one’s shoulder to see how things were done in the past, and what answers were then given. Part of the notion of “tradition” is a willingness to take seriously the theological heritage of the past.“
