First, contemporary takfir can be understood in plural but a well-balanced approach that all dynamics might be related to the takfir behavior. The effect of macro structural elements over the takfir act is not only changeable according to persons and groups, but also the social context of takfiris. Secondly, religious interpretation underlies the basis of takfir as a form of belief and perception. This form of interpretation and belief system is being taken shaped under effects of internal and external factors according to the model put forward in the article. The internal factors in the model explaining contemporary takfir consist of "takfiri salafi Islamic intrepratation opposite to Islamic orthodoksi", "written and translated ideological publications as the circulation lines of takfiri thoughts" and "the forms of relationships of the takfiris with authority in a vicious circle of reaction-pressure-reaction". The external factors that will be tackled in the second article of this series related to the prevailing one make up "modernizm crisis under negative effect of invasion and controls", "problem of political integration" and the social context of takfiri persons."
