That which is handed down, transmitted. Tradition is the life of the Church in the Holy Spirit, for the Holy Spirit leads the Church "into all truth" (John 16:13) and enables her to preserve the truth taught by Christ to His Apostles. The Holy Scriptures are the core of Holy Tradition, as interpreted through the writings of the Fathers, the Ecumenical Councils, and the worship of the Church. Together, these traditions manifest the faith of the ancient undivided Church, inspired by the Holy Spirit to preserve the fullness of the gospel. See John 21:25; Acts 15:1-29; 2 Thess. 2:15.
