"Ubi caritas" is a hymn of the Western Church, long used as one of the antiphons for the washing of feet on Maundy Thursday. Its text is attributed to Paulinus of Aquileia in 796. The traditional melody probably also stems from the late 8th century. It is now and then sung at Eucharistic Adoration and Benediction of the Blessed Sacrament and has for a long time been part of the Holy Thursday evening liturgy. The current Roman Catholic Missal (1970, 3rd typical edition 2002) reassigned it from the foot-washing mandatum to the offertory procession at the Holy Thursday evening Mass of the Lord's Supper. It also is found in current Anglican and Lutheran hymnals.
In the second typical edition (1975) of the current Roman Missal, the antiphonal response was altered to read "Ubi caritas est vera, Deus ibi est," after certain very early manuscripts. This translates as: "Where true charity is, God is there."
