The Congregation for Divine Worship (the Vatican committee that oversees all things liturgical) issued a response in 2000 to a request for clarification on this issue. In their response, they say that removing holy water from the fonts during the season of Lent is not permitted, in particular, for two reasons:
- This is an issue of custom, not law, and so the liturgical laws in place do not address this recent innovation. However, this practice "is contrary to a balanced understanding of the season of Lent, which though truly being a season of penance, is also a season rich in the symbolism of water and baptism, constantly evoked in liturgical texts."
- The fasting of Lent does not include fasting from sacramentals, such as the use of holy water.
The response continues: "The practice of the Church has been to empty the Holy Water fonts on the days of the Sacred Triduum in preparation of the blessing of the water at the Easter Vigil, and it corresponds to those days on which the Eucharist is not celebrated (i.e. Good Friday and Holy Saturday)."
In light of CSL’s statement and encouraged by the Congregation for Divine Worship, removing water from the font or preventing the faithful from touching the water in the font would be detrimental to the sign of baptism that is a focus of Lent. The baptized remain a baptized people throughout all of Lent. We do not pretend to be unbaptized along with the catechumens, just as we do not pretend that Christ is not risen during Holy Thursday or Good Friday. Our Lenten practices should more explicitly emphasize our baptism so that we can recognize those areas in our lives when we are not living out the promises of that baptism. What the faithful should be hungering and thirsting for is not the symbol of their baptism but rather a world in which the faithful living out of that baptism is evident. For the catechumens, their hunger for baptism may even be heightened when there are full fonts of water, just as a person who fasts is more aware of their hunger when food is placed before them.
It would be appropriate, as is our Church's tradition, to remove the water from the font after the Holy Thursday celebration, keep it empty during Good Friday and Holy Saturday, and fill it with new water at the Easter Vigil. One possible lenten option is to use a smaller piece of purple fabric that does not fully cover the font but adds some color to the area. In this way, the lenten color signifies the season while the water in the font is still accessible as a reminder of baptism for the faithful.
