In fact, all Christians the world over, if they knew, if they were told, would celebrate it, because it is part and parcel of the Easter celebration, the fifty days of Easter which include Easter Sunday, Ascension Thursday, the fortieth day of Easter, and Pentecost, the fiftieth day of Easter, all according to the Scriptures revered by all Christians, with the Catholics, as always, leading the way!
Hope for the world!
Google should take note! Would someone please baptize google! Inform google that Jesus Christ is Lord, not google (or facebook or youtube)!
