Christ is Risen!
The Tuesday of St. Thomas week is called Radonitsa, and known as the Day of Rejoicing.
On this day, and with Paschal Joy, we remember all who have reposed in the faith. Orthodox graves are blessed by priests and visited by the faithful.
It is hard for most parishes to gather at the graves on weekdays. So, the graves are blessed instead on St. Thomas Sunday, after the Divine Liturgy. When possible, this is followed by a traditional, joyous, communal picnic at the cemetery.
In any case, is important, to visit the graves of loved ones at any time during the 40 days of Pascha-tide; and to greet them saying or singing Christ is Risen…
For he is not a God of the dead, but of the living: for all live unto him.
Truly He is Risen!
