Dominum et vivificantem is the fifth encyclical written by Pope John Paul II. The encyclical was promulgated on 18 May 1986. It is a theological examination of the role of the Holy Spirit as it pertains to the modern world and the church and the use of spiritual prayer to renew one's spiritual life. This extended meditation on the Holy Spirit completed the Pope's Trinitarian trilogy of encyclicals, which includes Redemptor Hominis and Dives in Misericordia.
