So in Christian nations all around the world, Pentecost Sunday is a national Holiday. But how many of you can clearly remember what it is we all celebrate on this day?
Pentecost (Ancient Greek: Πεντηκοστή [ἡμέρα], Pentēkostē [hēmera], "the fiftieth [day]") is the Greek name for the “Feast of Weeks”, a prominent Holy event in the calendar of ancient Israel celebrating the giving of the Law on Sinai. This is still celebrated in Judaism as Shavuot.
