Q. 1. Is it true that the fonts in the Catholic Church are filled with water that was blessed during the Easter Vigil?
A. 1. According to "Paschales Solemnitatis," # 97, the fonts in Catholic Churches should be filled with water that was blessed during the Easter Virgil.
In accordance with Catholic tradition, the fonts are emptied after Holy Mass on Holy Thursday, They are later refilled with water that was blessed at the easter Vigil.
Reference: # 97 "Mass is to be celebrated on Easter Day with great solemnity. It is appropriate that the penitential rite on this day take the form of a sprinkling with water blessed at the Vigil, during which the antiphon "Vidi aquam" or some other song of baptismal character should be sung. The entrance steps to the church should also be filled with the same water." [Paschales Solemnitatis]
