Angelicalism

Heresy in the Spanish Inquisition Defined
The church had a very specific definition of heresy:
1. A heretic publicly declared his beliefs (based upon what the church considered inaccurate interpretations of the Bible); and
2. Refused to denounce them, even after being corrected by the authority;
3. He also tried to teach his beliefs to other people;
4. He had to be doing these things by his own free will, not under the influence of the devil.

Heresy in Islam (and Christianity in many ways)
In Islam, shirk (Arabic: شرك širk) is the sin of practicing idolatry or polytheism, i.e. the deification or worship of anyone or anything besides the singular God, i.e. Allah. Literally, it means ascribing or the establishment of "partners" placed beside God. It is the vice that is opposed to the virtue of Tawhid (monotheism). Those who practice shirk are termed mushrikun. Mushrikun (pl. of mushrik) are those who practice shirk, which literally means "association" and refers to accepting other gods and divinities alongside the god of the Muslims - Allah (as God's "associates"). In Islamic law shirk as a crime, can just be attributed to Muslims, since only a Muslim is legally responsible not to associate any partner to Allah.


Theurgy
Language and Fire were not created by our Species, and we are not in the 2nd Millennium. Our species, Homo Sapien, has been around for at least 100,000 years and language, through gestures, sounds and signaling, has existed for even longer, while the control of fire has existed for at least 1,000,000 years. Most people on Earth still have 1-4% Neanderthal DNA except for people living in Sub-Saharan Africa, who are 100% Homo Sapien and the only people who have the DNA of a third species are the Natives in Papua New Guinea, who have 4-6% Denisovan DNA.

“[T]he ‘exercise of religion’ often involves not only belief and profession but the performance of … physical acts [such as] assembling with others for a worship service [or] participating in sacramental use of bread and wine … .”
-Employment Div. v. Smith, 494 U.S. 872 (1990)

“Sacramental or ceremonial material shall be provided by the chaplain or volunteer worship leader and shall be used only in the area designated by the warden for the worship leader and shall not be in the possession of inmates at any time. These materials include:

a. Wine or grape juice, bread or communion wafers for Christian communion/mass;

b. Wine or grape juice, matsoh, raisins, nuts, and spices for Jewish ceremonial meals;

c. Tobacco, herbs, and pipes for Native American ceremonies;

d. Incense, candles and anointing oils for all faith groups.

Id. Mustafaa argues that this policy inhibits the free exercise of his religion because prayer oils are not distributed to Muslims at each of their five daily prayers.”

-Mustafaa v. Dutton, 958 F.2d 372 (6th Cir. 1992)

“Appellant argues that the religious use of peyote, a psychedelic hallucinogen, by Indians who are members of the Native American Church has been constitutionally protected by the Supreme Court of California in People v. Woody, 61 Cal. 2d 716, 40 Cal. Rptr. 69, 394 P.2d 813 (1964). He refers also to the California Supreme Court's decision in In re Grady, 61 Cal. 2d 887, 39 Cal. Rptr. 912, 394 P.2d 728 (1964), decided the same day as Woody, in which conviction of a "self-styled peyote preacher" for unlawful possession of narcotics, namely, peyote, was annulled and a new trial granted in order that the defendant might have an opportunity to prove that his use of peyote was in connection with an honest and bona fide practice of a religious belief. By parity of reasoning he contends that marihuana, another psychedelic drug, is entitled to the same constitutional protection as peyote. With due deference to the California Supreme Court, we are of course not bound by its decisions. However, we note an essential difference between Woody and the instant matter in that peyote in the Woody case played "a central role in the ceremony and practice of the Native American Church, a religious organization of Indians," and that the "ceremony marked by the sacramental use of peyote, composes the cornerstone of the peyote religion." Grady was apparently the spiritual leader of a group of individuals and provided peyote for the group which he said was for religious purposes.”
-Timothy Leary v. United States of America, 383 F.2d 851 (5th Cir. 1967)

I'm not entirely certain what is your central point or appeal, but it is interesting to see what people in so many very different cultures have believed throughout the ages.

Important too, to realise that if religious, one's own religion is by no means the only one ever developed, still extant or now extinct but all thought true by their own followers - but there are threads common to most.

Many faiths hold prior ancestries. Christianity's Judaic, Hebrew foundation itself drew heavily on Zoroastrianism. That was once a major but is now quite minor, faith, though still constitutionally respected in its ancestral home of Persia, now Iran.

Yet no new major, international faith has emerged since Islam about 1300 years ago, based distantly on the Hebrew ideas but respecting Christ as fully-human, not divine. Millenia-plus intervals might be typical, though.

...

The modern, rising popularity in what is very loosely called "pagan", does not make that a new faith; nor revive [i]an[/i] old religion. Instead it tends to create a broad, rather romantic, mish-mash of real ancient ideas and what its modern adherents think the ancients believed; from many different sources.

There are few if any genuine records, and descriptions of them by peoples of other faiths wanting to impose their own, are likely to be suspect to say the least. However, if they meet their followers' emotional or spiritual needs, it is for others to accept, not attack, them.
