Mat 5:48 Be ye therefore perfect, even as your Father which is in heaven is perfect.

This concept of "perfect" is also to be found in ancient philosophies.

My favorite is that attributed to Hermes - whether Hermes is an allegorical figure or historic matters little.  One does not need to believe a man named "Hermes" actually existed to study the message.

Over time, I find that to separate the material from the spiritual is more and more difficult.  Contemplating "LIGHT" from both the science and the spiritual/religious aspect gives me the idea that ALL is "light" and material is merely light that is more dense and has a lower frequency rate.

I've read of the quantum physics theory of NEUTRINOS.  (Please note, the use of "THEORY" ).  Briefly, in my own words, these are found to come from energy sources - mostly the sun - but, are also in radioactivity or nuclear decay.  These pass through matter - from our own bodies to passing through the earth.  It is thought that some of them that enter our bodies, stay there - as energy.

The Greek word for "perfect" is "telesma".   It is connected in the "ancient mystery schools" to: "rite" ("teleoo" means "to bring to an end" and "to initiate into the mysteries" ), also found in the word "talisman", a physical object whose subtle vehicle (or etheric double) is a condensation of a spiritual state of consciousness. All these meanings are implied here in philosophy of Hermetics:

The superforce accomplishing the miracles of the One Entity, according to the laws of the operation of the Sun, brings everything to its natural end, i.e. towards its completion, i.e. its return to the One Entity.

Basic Hermetic philosophy:

"We are capable of finding divinity within ourselves and nourishing it by using Inner Fire --  this akashic matter, this cosmic electricity, which Hermes Trismegistus in his Emerald Tablet called telesma. By whatever name, it is always the same primordial force, 'the most powerful force of all forces' as Hermes Trismegistus calls it. This force comes from the sun, which is the distributor and inexhaustible source. One of the manifestations of this force is love -- love which makes the worlds move. Behind the light of the sun are many other forces, and telesma is a force so potent that, as the Emerald Tablet puts it, ‘it overcomes every subtle thing and penetrates every solid substance.' The initiate’s work is to channel this telesma and condense it within his cells until a transformation takes place.” Hermes said, in the Emerald Tablet, “It is the cause, this, of all perfection of all things throughout the universe. This will attain the highest perfection of powers.” 

This "telesma" of Hermetics, and "perfection" spoken of by Jesus, as something we should have as a goal certainly sounds like it is related to the scientific theory of NEUTRINOS to me.  (And, there are thought to be, "ANTI-NEUTRINOS" ).  

BTW, The origin of the word Hermes relates to a stone pillar used to communicate with the deities and the use of names beginning with Herm in Greece dates from at least 600 BCE.

As a Greek god, an ancient mention is in the "Homeric Hymn to Hermes", dating to the seventh or sixth centuries BC and deals with his birth and early exploits.

Thus, the antiquity of the roots of Hermetics (back to Hermes/Thoth) are evident.
