This text encapsulates one of the most important themes of this upcoming holy week: Christ’s willing sacrifice on the cross for His (and our) eventual glorification. We could all do well to meditate upon this text as we enter this sacred week.
Christus factus est pro nobis obediens usque ad mortem, mortem autem crucis. Propter quod et Deus exaltavit illum et dedit illi nomen, quod est super omne nomen.
Christ became obedient for us unto death, even to the death, death on the cross. Therefore God exalted Him and gave Him a name which is above all names.
This text is specifically from the Palm Sunday Mass, Good Friday Liturgy, and for the office as well. It’s also used for the Exultation of the Holy Cross, and on Holy Thursday in the EF.
