It's 'tenets' you illiterate christfag jewslave
Anyway, the tenets and dogma can be described thusly:
The smallest unit is not the individual, but the tribe. Heathenry bases itself, as in pre-christian times, in the idea of tribalism a community. Everything that you do is representative of your tribe, clan, hearth, and inneangearde. These terms are all different meanings, and too complicated to get into here, and even then it is a watered down version of what our ancestors actually believed, because of limited evidence only allowing to piece together a half-finished picture. Anyway, the easiest way to think of a tribe is as your local community; those you interact with on a day-to-day basis. If you live in the USA, and then go and live on a small farm in, say, North Korea (example because most of them won't have met an American before), these North Koreans, who have never met an American before, will see the way you act and assume that it is how all Americans act. It's basic human nature. This reaches down into the smallest unit, the tribe, which tells the same story. If you go to a different part of your city which doesn't normally interact with your part of the city, how you act there will be representative of how people from your neighbourhood (your tribe) act. everything you do is representative to others of how your people act, be it, your ethnic group, your countrymen, your city, or your tribe. This is how we approach divinity. We do not approach it as individuals but as a tribe. When the gods see you giving offerings, they see you as a representative of your tribe, not as a single person, as Christianity sees it. You do not have a personal relationship with your gods, you have a collective relationship. I could get into other facets of Heathenry, but that is the most important. That, Frith, and oaths (I won't get into Wyrd and Orlog here)
Frith is the peace that you are guaranteed when you are with your tribe. When you are amongst your own, you are safe. If not, where can you be safe? Breaking the Frith (i.e causing a conflict within a tribe, like having a rather vicious argument with another member) is considered one of the worst things you can do in Heathenry. This brings me on to Oaths. Oaths are sacred promises. It's more than a promise. It's like swearing on the bible for Christians. It's probably the worst thing you can do.
I could be here all day telling you ritual procedures. Would you prefer a regular one, or a festive one?
Valknut, Swastika, Mjolnir?
