Gregorian Chant: Justus es, Domine | Introit for Seventeeth Sunday after Pentecost |Graduale Romanum

This is the Introit for the Seventeeth Sunday after Pentecost (Dominica XVII post Pentecosten) from the Graduale Romanum. This chant is in Mode I (1). My goal for this channel is to sing the Introit from the Graduale Romanum for each liturgical week. Hope you enjoy the video! The Latin text is taken from Psalm 118, verses 1, 124, and 137: Iustus es, Dómine, et rectum iudícium tuum: fac cum servo tuo secúndum misericórdiam tuam. Beáti immaculáti in via: qui ámbulant in lege Dómini. ℣. Glória Patri, et Fílio, et Spirítui Sancto. ℟. Sicut erat in princípio, et nunc, et semper, et in sǽcula sæculórum. Amen. Iustus es, Dómine, et rectum iudicium tuum: fac cum servo tuo secúndum misericórdiam tuam.
