Apostolic foundation is a summary statement of faith whose purpose is, from the beginning of the Christian church, to briefly testify about basic points that encompass the purity of the Father's Doctrine. It was revealed by His Son the Lord Jesus Christ during His ministry. Then, with the advent of the Holy Spirit, it was given to four evangelists and the Apostles by divine inspiration; who, affirming themselves in the Law, the prophecies and the Psalms, wrote the gospels for the world and the epistles for the church.
