To the Holy Spirit
*Veni, Sancte Spiritus* — the great hymns, the novena, the triduum, and the Litany of the Spirit Who is the soul of the Church.
Between the Ascension and Pentecost, the Apostles and Mary spent nine days in the upper room — the first novena. Every prayer to the Holy Spirit since stands in that same waiting. The Church begins councils, opens schools, ordains priests, and starts retreats with the same hymn: Veni, Creator Spiritus. Pentecost is not last year's feast; it is the air she breathes.
Hymns & Sequences
Veni Creator Spiritus — the ninth-century hymn; Veni Sancte Spiritus, the Golden Sequence of Pentecost; and Come Holy Spirit, the simpler invocation.
