What is your definition of spiritual?
Do you not see scientific delving and discovery as a path of discovering the higher power?
Can having faith in Nature and Natural Law not also be faith in the will of TGAOTU?
Masonry is VERY literal, the words are chosen with great precision, to the highest degree of understanding of those who wrote them, anyway. If we discount communication through language, either spoken or written, as not being "literal" that is, not true to it's symbolic representation of ideas, then are we really communicating. People like to say, "Oh that's just semantics," but semantics is the study of meaning. Language is a code, it is abstract symbols used to convey concrete ideas.
Nature's Laws teach us how to live. The study of Nature and connection to it provides comfort to many who put their faith in it. The material world, our Universe is our home, it's design and manifestation "by word alone" as the allegory goes, by the Creator or TGAOTU, and in it's design and geometry, as manifest word, we see the allegories of much that any written word of man only pales in comparison with. In my opinion.
For me story and allegory and scientific knowledge are spiritual. The spiritual gift of knowledge is also known as the “word of knowledge” or “utterance of knowledge.” The Greek word for this gift is Gnosis and it simply means knowledge and understanding. The Scriptural emphasis in 1 Corinthians 12:8 is on the ability to speak this knowledge to others in a given situation.
It has been said that God is the author of such knowledge; and that
flesh and blood reveals it. Mortal men are capable of imparting the knowledge of human arts and sciences, and skill in temporal affairs. God is the author of such knowledge by those means:
flesh and blood is employed as the
mediate
or
second cause of it; He conveys it by the power and influence of natural means. This to me is also is Spiritual Light.
I hope that my comments and contribution to this discussion can fall on some receptive ears who are open to receive it, and thereby, gain more Light and grow closer to men of other wisdom traditions besides those of written word and organized religions.
