Gradual Rationality of Religious Beliefs System

A creature that all of devine religious in some ways has emphasized on, is Holy Spirit. From the point that God is the common axis of all devine religions in Holy Book in which has introduced this devine truth to all the Human Beings. All the devine religions has talked about a unit truth although there are some superficial disagreements. This text tries to introduce Holy Spirit in two religions of Islam and cristianity and clarify the usage and the similar and dissimilar points according to Bible, Quran and Islamic narations through using religious sources and analysis of data via library method and analytical – comparative methods. We will be guaided to a point in which all the cristians beliefs place Holy Spirit in side with God and Crist and gives him a devine position and believe that he is the third side of Trinity. This spirit plays a huge role against the Jesus and after the ascension of Christ this spirit holds the responsibility as a leader for religious comminuty and for the followers brings a lot of blessings.We have several citations of “spirit” and “Holy Spirit” in Quran.Alghough a plethora of interpreters specially Suni ones has appointed “Holy Spirit” to Gabriel, according to narrations we reach a conclusion that Holy Spirit is far more superior to material of angels, and is superior to Gabriel and Michael too, and he has enormous blessing for the person who possess it.
