Come Holy Spirit!
The Novena is from June 3-11 this year. The apostles gathered together in the upper room with Mary, the mother of Jesus, where they prayed for nine days the first novena, from the Latin word for nine, novem. It was here that the Church was born by receiving the promised Gift of the Paraclete. SOLT has compiled a Pentecost Novena from Blessed Pope John Paul II's Encyclical on the Holy Spirit, Dominum et Vivificantem.
Here is an ancient hymn, Veni Creator Spiritus, which is an excellent catechesis on the Holy Spirit.
