Angels are spiritual beings present in all major monotheistic religions. The idea of a mediator between God in heaven and people on earth has existed since the beginning of time. God is a Mystery and remains a mystery to people on earth. Because of this, but also because of God's holiness and human sinfulness, God most often reveals himself to people through angels, i.e. in angelophanies, which mean the manifestation of angels to people in a way that they can see. In the Holy Scriptures, this can happen in various ways, but mainly in sleep or by stimulating our senses such as sight and hearing. Angels appear at the beginning of the Holy Scriptures and are present until the end when their role will be fully expressed. They are God's messengers, convey God's messages to people, and carry out God's commands on earth, acting in various ways in various forms. There are many angels of God and in The Middle Ages angels were divided into The Nine Choirs of Angels. Saint Thomas Aquinas gives us a philosophical view of angels as spiritual beings who can not perish since they are not made of matter and form. Angels are rational beings with free will created by God. Based on the Bible and philosophical thought, it can be said that the human history of salvation is also the history of angelophany because God most often saves his people through angels. This especially comes to the fore in the Old Testament, i.e. before God came down to earth and became human in Jesus Christ to be closer to his people.
