It doesn't get the same liturgical attention as Maundy Thursday, Good Friday, or Easter Sunday, because, formally speaking, nothing happens.
used in the Great Saturday liturgy.
Jesus' friends laid him hurriedly in the tomb Friday in advance of sunset and Sabbath. And then they laid low. The gospels go silent until Sunday morning, about 36 hours later.
Any and all the action is off-stage, buried in the ground, hidden behind the stone, shrouded in the Great Mystery.
Tradition has not been able to be as silent as the gospels and has filled in the blanks with two competing stories. The Matins Canon of Holy and Great Saturday has a tone of watchful expectation, with Jesus observing Sabbath rest.
Today Thou dost keep holy the seventh day,
Which Thou has blessed of old by resting from Thy works.
Thou bringest all things into being and Thou makest all things new,
Observing the Sabbath rest, my Savior, and restoring strength.
This is, of course, something the church believes as true. In the Great Vigil of Easter, the Church will sing the Pascal Troparion:
Christ is risen from the dead, trampling down death by death, and upon those in the tombs bestowing life!
We live post-Easter. Thankfully, we cannot un-see or un-know that wonderful news which we have embraced.
Yet Great Saturday is an opportunity to reflect on that moment where we cannot see God's plan. Whatever was going on behind the scenes, to the world it looked like yet another troublemaker put down. The devil wants you to know that resistance is futile. "March all you want, but I can and will kill you with impunity. Your best hope is to submit." These temptations (really threats) are the same whether from the Roman Empire or the Domination System of this age.
It's a choice that takes your breath away. But...it...is...not...true. Can we trust just a little longer? Can we dare to hope in the face of fear?
With the Lord on my side I do not fear.
What can mortals do to me?
The Lord is on my side to help me;
I shall look in triumph on those who hate me. Psalm 118:6-7
Two thousand years ago, everyone buried Jesus. To this day, there are forces which would prefer this inconvenient God to keep silent and make no demands. Can we be faithful and not abandon the reality of God's blessing? Can we be faithful just another day? Can we deny the devil no matter how strong its position seems? Keep your eyes on the prize, and hold on. The dawn is coming.
You are my God, and I will give thanks to you;
you are my God, I will extol you.
O give thanks to the Lord, for he is good,
for his steadfast love endures forever. Psalm 118:28-29
