During this week, the Holy Church concentrates on one subject: The Lord Christ’s suffering. For this reason, the Psalm readings and the Canonical Hours which cover various subjects relating to the Lord Jesus Christ including His birth, His ministry, His Resurrection, Ascension and sitting on the Father's right hand and His Second Coming in His Glory, are replaced by a special hymn chosen by the Church especially for the Semmune Himmamat.
The details of the special hymns of Passion Week can be found in the following PDF file.
