Throughout the centuries, the use of the mantilla by women has had many purposes. The wearing of the Mantilla is an act of veiling a woman's physical beauty, so that the beauty of God may be glorified instead. It is also a way of emulating, Mary, our mother, who is the archetype of purity and humility. Moreover, the mantilla, or chapel veil, signifies the role of women as a life-bearing vessel. The chalice holding the blood of Christ is veiled until the Preparation of the Gifts, and the tabernacle is veiled between Masses. Both of these vessels hold the Eucharist – the very life of Christ. In a similar fashion, the woman was endowed by God with the special gift of bearing new human life. Because of this, women, as all things holy and sacred, are veiled.
