We may classify the records of the Christian exploration roughly in three groups. In the early Christian centuries, we find endless thought given to the philosophical study of the relation of Christ and God. It fills the library of the Early Church, and practically all the early controversies turn upon it. The weak spot in all this was the use of the "a priori" method. Men started with preconceptions about God--not unnaturally, for we all have some theories about God, which we are apt to regard as knowledge. But knowledge is a difficult thing to reach in any sphere of study; and men assumed too quickly that they had attained a sound philosophical account of God. They over-estimated their actual knowledge of God and did not recognize to the full the importance of their new experience. This may seem ungenerous to men, who gave life and everything for Jesus Christ, and to whose devotion, to whose love of Jesus, we owe it that we know him--an ungenerous criticism of their brave thinking, and their independence in a hundred ways of old tradition. Still it is true that the weakness of much of their Christology--and of ours--is that it starts with a borrowed notion of God, which really has very little to do with the Christian religion. To this we shall return; but in the meantime we may note that here as elsewhere preconceptions have to be lightly held by the serious student. Huxley once wrote to Charles Kingsley: "Science seems to me to teach in the highest and strongest manner the great truth that is embodied in the Christian conception of entire surrender to the will of God. Sit down before the fact as a little child, be prepared to give up every preconceived notion, follow humbly wherever and to whatever end Nature leads, or you shall learn nothing .... I have only begun to learn content and peace of mind since I have resolved at all risks to do this." So Huxley wrote about the study of natural science. In this great inquiry of ours we have to learn to be patient enough--we might say, ignorant enough--to do the same. The Early Church had a faith in Greek philosophy, which stood in its way, brave and splendid as its thinkers were.
