"677. The Church will enter the glory of the kingdom only through this final Passover, when she will follow her Lord in his death and Resurrection. The kingdom will be fulfilled, then, not by a historic triumph of the Church through a progressive ascendancy, but only by God's victory over the final unleashing of evil, which will cause his Bride to come down from heaven. God's triumph over the revolt of evil will take the form of the Last Judgement after the final cosmic upheaval of this passing world."What will this "death of the Church" be like? The Catechism itself presents not a few hints (675-677):
"The persecution that accompanies her pilgrimage on earth will unveil the "mystery of iniquity" in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. the supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh "(675-677).
On the other hand, does the death of Jesus shed light on the "death of the Church"?
The Catechism teaches that "Jesus did really die" (636), meaning His Soul was separated from His Body, and that during "Christ's period in the tomb, his divine person continued to assume both his soul and his body, although they were separated from each other by death. For this reason the dead Christ's body 'saw no corruption'⇒ Acts 13:37)" (630) ...
... food for thought or for meditation in front of the Blessed Sacrament, if the present crisis did not rob you of the ability to meditate.
Now, I do not know if we are going through what the Catechism calls the "Church's ultimate trial" - probably not.
But even if this is just a (un)holy Saturday of the Magisterium there are more practical lessons to learn from Christ's stay in the tomb.
"188. Saturdays stand out among those days dedicated to the Virgin Mary. ... it is a remembrance of the maternal example and discipleship of the Blessed Virgin Mary who, strengthened by faith and hope, on that great Saturday on which Our Lord lay in the tomb, was the only one of the disciples to hold vigil in expectation of the Lord's resurrection... it is a sign that the 'Virgin Mary is continuously present and operative in the life of the Church'"
We could do worse than spend the present looong (un)holy Saturday of the Church in the company of the Blessed Virgin Mary. For me this means praying the Rosary and practicing whatever Marian devotions God inspires me to pratice.
So, it's time to study Saint Louis-Marie Grignion de Montfort's "Treatise on the true devotion to the Blessed Virgin" (versão portuguesa).
I pray I won't have time to memorize the whole thing...
