In the early 20th century there lived a young priest named William Temple. Like many people in the world, William had doubts regarding his christian faith, specifically in respect to the doctrine of the Virgin Birth. As a young priest William began to feel insicure teaching it and despaired that he had no choice but to leave the priesthood behind. However, William made the important decision to continue questioning his faith, rather than leave it behind. Many people in the world believe that doubt is the opposite of faith. However, this is not so. The opposite of faith is despair. Like Williams, each of us will struggle with various doctrinal questions, but we need not suffer in the process.
One of the most hotly contested doctrines throughout history has been that of the Trinity. The trinity first became prominent in Christian thought early in the 100's AD. While the trinity is still considered a great mystery of the Church, it's important to note that the doctrine as we understand it today was not formalized until the Council of Nicaea in the 4th Century. Even then the creed seemed to have been an uncomfortable compromise for it's authors, who had doubts themselves.
One of the beautiful things about our faith is our chance to question the answers, doubt the wonders, and ponder the mysteries. In fact, it is the duty of a Christian to doubt—because doubt is part of faith. Through continuous appeal and examination we develop a richer understanding of God and his creation. Through doubt we develop confidence, which coincidentally in the latin means "with faith." When we put our confidence in the Lord we endure with him, and he endures with us. So our prayer is this: that we may doubt with confidence, that we may abide with the Lord and in his care.
