The surplice, a sacred object used in Catholic worship, is a long, white garment resembling a tunic. Its simple design, typically with wide sleeves, belies its important role. Used in liturgy, it's worn by various ministers during Mass and other services. The surplice's symbolic meaning represents purity and simplicity, focusing attention on the sacred act rather than the wearer. Its white color signifies the cleansing grace of Christ, while its loose fit conveys humility.
