Francis the Pope tells us: "those who serve the truth serve Christ." In his TheoDrama (Vol. 1), Han Urs von Balthsar tells us to do the truth. Does anyone really believe that you do the truth? Now, what does this look like? Preach with your life the Paschal Mystery, that is, Jesus Christ Present: here and now.
Perhaps a reflection from Saint Cyril of Alexandria might help us understand: "When the disciple Peter had professed his faith, Jesus charged them, it says, and commanded them to tell it to no one. 'For the Son of Man', he says, 'is about to suffer many things, and be rejected, and killed, and on the third day he shall rise again.' Wasn't it the duty of disciples to proclaim him everywhere? This was the very business of those appointed by him to the apostleship. But, as the Scripture says, 'There is a time for everything.' There were things yet unfulfilled which must also be included in their preaching about him. They must also proclaim the cross, the passion, and the death in the flesh. They must preach the resurrection of the dead, that great and truly glorious sign by which testimony is borne him that the Emmanuel is truly God and by nature the Son of God the Father...He commanded them, therefore, to guard the mystery by a reasonable silence until the whole plan of the dispensation should arrive at a suitable conclusion."
