Well I have been looking for some kind of statement of belief from the original worshippers of my patron deity and I have come up dry. So it looks like I have to make one for today’s followers, based on my biases. That’s part of the problem when the original religion was a secret society that passed knowledge as an oral tradition.
First is the only thing required to follow Hephaestus is the desire to make things. All the things from all the materials are sanctified provided they are made with the proper attitude. Even making meals is sanctified if for no other reason than continuing your existence.
Second there are no races/ethnicities better than any other races/ethnicities. If you make things you can follow Hephaestus. All are brothers and sisters at the forge.
Third you must strive to make things that improve the human condition, at least part of the time. Weapons are allowed for defensive purposes and as an art form. Weapons training resembles dance in many ways. Making weapons one must be sure to make them only as deadly as required for the purpose, followers should never make WMD.
Fourth if you have a choice between making something and making something beautiful that serves the same purpose, make it beautiful, but if your choices are ugly but serviceable or nothing at all make something serviceable. Work on your skills until you can make the thing beautiful the next time you need to make it.
Fifth Hephaestus did not require sexual fidelity from his wife, so we should not bind our partners to us so that we deny them the company of others. Love is not a chain to bind us but a thread to guide us back together when we are ready. Love grows best when it doesn’t bind. Also celebrate your partner’s(s’) accomplishments, recognize what they do even when it’s not about you. They are separate individuals with separate needs and desires. Celebrate when you can be together but do not mourn if you are apart.
Sixth plagiarizes another religious statement, Love your brothers and sisters as you would yourself, everything else is just commentary.
Go in peace, and make something wonderful.
