The distinction between institutional and non institutional Christianity, consists in the fact that, in the early Christian Church, the spiritual element was more present than the institutional one. It was a time when the institution was not there, it only started to be formed gradually. The Christians were persecuted and their communities were based on the direct guidance of the Holy Spirit, rather than on the exegesis of the written texts of the canonic Bible. There was a risk being Christian. I refer to the risk of martyrdom. During the apostles’ era, only people truly called by God came to God.
