Organ,Voice - Level 3 - SKU: A0.1406751 By Cathy Lundeen, Vocal / Dr. Sheri Masiakowski, Organ. By Sr. Theophane Hytrek OSF. Arranged by Dr. Sheri Masiakowski. 20th Century,Religious,Sacred. Full Performance. Duration 160. School Sisters of St. Francis #989486. Published by School Sisters of St. Francis (A0.1406751). “The Spirit of the Lord† Sr. Theophane Hytrek OSFCathy Lundeen is currently a choir member and cantor at St. Luke Congregation in Brookfield, Wisconsin under the direction of Shawn Rochon. She is also a member of the School Sisters of St. Francis Chapel Singers directed by Sr. Bernadette Luecker OSF, as well as a member and coordinator of the Gaudete Chorale, directed by Brian McLinden.Cathy credits her vocal “training†and love of music ministry first and foremost to her sisters Laura Monteen, a retired Director of Liturgy and Music for the Gary Diocese, Indiana and Nancy Johnson, currently a cantor and choir member at St. John Neumann Parish in Homewood, Illinois, as well as liturgical music mentors Sister Mary Jane Wagner, OSF, Sister Bernadette Luecker, OSF, Brian McLinden, Shawn Rochon, Fr. Kenneth Augustine, Fr. Charles Conley,  Ann Owen and Bill Erickson. TEXT:The Spirit of the Lord is upon us. Send your Spirit upon us in this time and place, the Spirit who gives us comfort, the Spirit who brings light to our eyes, the Spirit who helps us say yes to your summoning Word.Bless us, Father, as you have done before, with the gift of your Spirit that he may stir new life within us.Blest are you in ev'rything that your Spirit makes new, now and for all ages to come.The source of this text is unknown. Though appropriate for Pentecost there is no direct connection to the scripture readings or sacramentary prayers for that Feast. The composition was written in the early years succeeding Vatican II (October 11, 1962 – December 8, 1965), a time of creative freedom. The language is period specific to that time, yet the music is universal.We invite you to browse other creative works by the School Sisters of St. Francis on our website:  https://www.sssf.org/SSSF/Our-Global-Impact/United-States/Music-Ministry/Catalog-of-Music.htm  Further information about our offerings is available from Dr. Sheri Masiakowski, curator of the Heritage Music Collection, at smasiakowski@sssf.org.
