[5] Adoro te devote is one of the medieval poetic compositions, being used as spoken prayers and also as chanted hymns, which were preserved in the Roman Missal published in 1570 following the Council of Trent (1545–1563).
[12] This hymn was added to the Roman Missal in 1570 by Pope Pius V, and also it has more quotations in the Catechism of the Catholic Church (n. 1381).
There are modern musical settings and arrangements by Alexandre Guilmant (Offertoire sur Adoro te devote for organ, 1908), Cecilia McDowall (2016), Carlo Pedini (2021) and Healey Willan (chorale prelude, 1954).
Until the first half of the nineteenth century, the (Eucharistic) chant Adoro te devote was often used to be followed by this second Thanksgiving prayer, referred to Jesus Christ God: On 13 December 1849, Pope Pius IX stated a period of 3 years of indulgence.
