Looking at the second paragraph, upon much meditation of the subject, at least to me, it sounds like it is describing all things in this Universe as coming from God and are of God (which sounds closely similar to St. Thomas Aquinas' concept that God is the source, "un-caused cause", and primary force of motion in all things; Isaac Newton practically said the same thing with his Laws of Motion). The second paragraph also seems to be telling us (interpreting it through a Christian lens) that we should follow Christ. His Way is the way to perfection and balance of Mind, Body, and Spirit (represented in Alchemy as Sulfur, Salt, and Mercury). One would ask, "But where is the Soul in all this?" Well, alchemists attested that the Mind and the Soul were the same thing. A way to confirm this is in listening to Christ when he told us that to imagine having intercourse with someone is the same as the physical act of it.
Paragraphs three and four describe the 7 Alchemical Processes:
And yes, these are also the steps in modern, spiritless chemistry. But they are also the steps of the many things that we practice in our faith. We can even compare these seven steps to the Creation in Genesis and the before, during, and after of the Crucifixion of Jesus Christ. We can even correlate these seven stages to the Holy Mass, and there are even 7 Sacraments.
I don't want to take too much space discussing such correlation here, but if you'd like to find the inherent similarities between the Alchemical Processes and the Creation/Crucifixion/Holy Mass then be my guest and follow this link -> alchemylab.com/contents_solar.htm#TABLE OF CONTENTS and scroll down to "Operations of Alchemy". All seven are there and the links for them describe the intellectual/soulful, spiritual, and physical manifestations of each step.
Example: Calcination involves the heating, burning, or destruction of a substance (i.e. the Scourging at the Pillar, The Crucifixion, and Christ's descent into Hell). Mental/Soulful and Spiritual Calcination is the destruction of Ego and of our attachments to the material world (i.e. The Agony in Gethsemane, Christ's 40 Days of Fasting, The Tempting of Christ).
The last paragraphs basically confirm that the 7 Alchemical Processes are derived from the steps God took in the Creation depicted in Genesis; 6 days of Creation and 1 of Rest. Now, where the Tablet says "Hence I am called Thrice Greatest Hermes..." In Greek mythology, Hermes was the messenger god, the medium through which the Heavens could communicate to those on Earth and give those on Earth the knowledge needed to balance the Mind/Soul, Body, and Spirit. Of course there is no such thing as Hermes, so the Tablet must have mistaken an identity through the lens of Grecian mythology. The clue to who it "really" is lies with the phrase "Thrice Greatest", or from the Latin "Trismegistus". This, of course, is the title of which we give God when we identify Him as the Holy "Trinity".
So if Hermes Trismegistus wasn't Hermes but God Himself then where is this Emerald Tablet in the Bible? It is in Exodus 24; verse 12: And the Lord said to Moses: "Come up to me into the mount, and be there: and I will give thee tables of stone, and the law, and the commandments which I have written: that thou mayst teach them." Notice the structure of the sentence; God gave Moses "tables of stone" and (IN ADDITION TO) "the law" and "the commandments".
In conclusion, I cannot see how Alchemy, in this Christian sense, which must undoubtedly be the Truth, would want to be abhorred by Christians and abolished by the One Holy and Apostolic Church. Obviously, as purported by Exodus, God had given "tables of stone" to Moses in addition to the law and commandments. Of these tablets, surely, must have been the Emerald Tablet. And notice that God gave Moses 3 items (the tablets, law, and commandments). It is through Alchemy that God gave us the formula to connect and observe His Will in all aspects and in the balance of Mind/Soul, Body, and Spirit, and it is the Bible which is the recipe book.
