According to Christian beliefs, God is one, but represented in three persons. He is the Father, the Son, and the Holy Spirit. In other words, the Holy Spirit is one of the manifestations of the Creator, part of the indivisible Holy Trinity. It is difficult for those who come to the Christian faith and try to comprehend its foundations to understand this issue and imagine such an intricate nature of God.
The Holy Spirit in Judaism
The Holy Spirit is already mentioned in the Old Testament, although it is not mentioned there very often. More often in the Holy Scriptures you can find just a reference to the "spirit" or the "spirit of God." In the Jewish religion, even in those distant times, when the Old Testament was compiled, it was believed that God is one. Any idea of the duality or trinity of the Creator was considered a heresy among Jews.
Speaking of the "spirit of God, " the Jews had in mind divine power, which, although it has a personal coloring, but remains a property that belongs to God as one of its indispensable attributes. This is the difference between Judaism and Christianity, where the Holy Spirit is part of the triune God.
In Judaism, the Holy Spirit is thus perceived as a force actually acting in the world, divine breath. Everything that God does is pervaded by his spirit. But Orthodox Jews never perceived the Spirit of God as a person; this is characteristic of the Christian religion.
