The Native faith renews the origin pre-Christian faith of Slavonians of Czech lands. This pre-Christian religion of Slavonians of Czech lands is a part of generally common Slavonic religion. In general, the Slavonic religion belongs to the Indoeuropean branch of religions. Indoeuropean religions are bounded with the other Euroasian religions and their anthropological signs are generally identical with the other origin religions of whole world.

Unfortunately, Slavonic religion has not been passed on till these days in its entire form. That´s why we have to reconstruct and renew this religion. Reconstructed and renewed Slavonic religion is called Slavonic native belief. The other names for this are for example Slavonic religion, Lingualism, Antic belief, Perunism etc. All of them express one common phenomenon. Only authentic sources are being used for the reconstruction of Slavonic religion. These are the sources which authencity is generally accepted by specialists. That´s why we cannot use for reconstruction such sources with disputable credibility like Czech Manuscripts or the Word about regiment of Igor because then the base of faith could be done in a wrong way. From the same reason we also reject the texts which specialists marked as a fake like e.g. Book of Veles or Veda of Slavonics. From the reason of disability of validation we cannot use for the reconstruction some kinds of revelations, visions or illuminations of individuals or words of a person who considers himself or is considered by the others to be chosen, enlightened or predicted in any way.

In case of Czech variant of Slavonic religion we take inspiration mainly from a few sources, a bigger numer of archeological ones and many rich ethnographical sources. We are obtaining the entire imagination by the completing these dates with the results of historical and comparative analyse of the other Slavonic sources mainly by the recovering of the origin ancient Slavonic status and by the similar analyse of the other Indoeuropean sources.

As the other Indoeuropean religions, the religion of Czech Slavonians is the polytheistic religion, therefore the generally taken deity is shown in many divine individualities which are gifted by their own will. These divine individualities – gods and goddess – are mutually bounded by the relationships of many characters, their hierarchal status is also characteristic. Great grand-father, the father of the other gods and supreme god of heaven Svaroh (lokal form is probably Svantovit) stands on the highest point of pantheon. The other gods are as nobler as closer to him by his bloodline. These are for example the clasiccal Indoeuropean ruler of thunder Perun, the ruler of the underworld Veles or the god of sun Dazboh. Their counterbalances are female goddesses where the mother of the earth Mokoš is the most significant.

Every natural polytheistic religion also contains the other older phases of religious thinking as animism, manism or totemism. They are visible in Slavonic religion as well, the important part of it is manism (the cult of ancestors). We can find the veneration of various natural spirits in animism (the fairies, the water sprites, the forest men and the forest women etc.) an totemism is visible in the cult of plants – mainly of trees (for example the oak-tree which is devoted to Perun) and of animals (the ox, the horse, the wolf, the bear etc.).

A big part of spiritual customs of each natural religion is also magic which appeared in the oldest times. Magic is manipulating with unnatural strength where the phenomena are connected with all levels of polytheistic religions in order to influence the other phenomena. We can distinguish the types of magic according to which level of religion the magic is used. The oldest is the magic of nature which is manipulating with the strength of wild nature for the purposes of healing of illnesses or for ensuring the success during the hunting. The younger level is the agricultural and pastoral magic with the primary task of ensuring the harvest and prosperity. The youngest level is the social magic which was used by more developed pagan societies where the differenciated communities had a special section of priests and warriors. This level of magic is dirrectly connected with cults of polytheistic gods. All of these levels are used in Slavonic religion. A special form of magic is prophecy and its different forms have been preserved among Slavonians till these days.
