Linggo ng Palaspas, Palm Sunday, celebrates Jesus Christ's entry to Jerusalem for the Jewish festival of Passover, with crowds of people waving palm branches to welcome him. The raising of Lazarus from the dead performed by Jesus gained him popularity in Jerusalem where he was to fulfill the words in the Scriptures on His final days.
Decorated palaspas, palm fronds, or smaller ones bought from early-morning vendors are brought to the church by parishioners to be blessed by the priest. The procession that follows sees the waving of these fresh palaspas, in memory of the Christ's triumphal entry to Jerusalem. These are then brought home and kept in altars, or behind doors and windows to drive the evil spirits away for a year. Then their potency would have waned by then so that they would be replaced with new ones on the next Palm Sunday.
