Appropriate Symbolism
Regardless of the drawbacks and handicaps, every new revelation of truth has given rise to a new cult, and even the restatement of the religion of Jesus must develop a new and appropriate symbolism. Modern man must find some adequate symbolism for his new and expanding ideas, ideals, and loyalties. This enhanced symbol must arise out of religious living, spiritual experience. And this higher symbolism of a higher civilization must be predicated on the concept of the Fatherhood of God and be pregnant with the mighty ideal of the brotherhood of man. 87:7.6
