Happy Good Friday
Christians will be observing Good Friday in much the same way the Jewish families celebrated Passover this year: Social Distancing to save lives.
All of Christianity for those that Believe that Christ Jesus was Born, Lived & Died on the Cross for our Soul Salvation is based on the Betrayal at "The Last Supper" as depicted by Leonardo Da Vinci.
Betrayed by a Kiss in the Garden of Gethsemane, this is the origin of Christian Traditions of all Denominations from Catholics to Protestants, as related in 1 Corinithians 23-25: below:
23 For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, 24 and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.” 25 In the same way, after supper he took the cup, saying, “This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me."
