On Palm Sunday, Armenians receive blessed palms in memory of the glorious procession of Jesus into Jerusalem. We read in John 12:12-13 how people "took branches of trees and went out to meet him, crying, 'Hosanna'..." Traditionally these palms are fashioned into small crosses and displayed in the home.
