It's always a little scary, talking about intention, disposition and receiving the Sacraments. Yet, it is a fairly frequent question that comes up when a person with special needs wishes to receive the sacraments, and particularly when it is a person who has a developmental or mental disability. But, it is a good question- how do we know if a child or adult who in some instances cannot communicate their intention and understanding outwardly, can validly and fruitfully receive the sacraments? The first and shortest answer is, disability in and of itself is never a reason to delay or deny a sacrament. I'll be sticking mostly with the Bishops on this one, but will be adding some commentary along the way, and I'll include a link to the full guidelines at the end.
Sherry Weddell describes a "positive disposition" as when a person embraces "
both the sacramental sign,
and the inward reality." A sense of the sacred, and a "positive disposition" can be found in surprising places. There is a friend in one of the SPRED groups who is known to close his eyes and raise his hands in prayer while the Scripture passage is being read. He was also the one to express that though he was frustrated at the loss of some of his freedom when he was hit by a car (for the second time) he sees God working in his life, giving him opportunities to grow and renew himself. That is a kind of trust and hope that I can look to as an example.
A "positive disposition" can look different from person to person, particularly when it comes to those with special needs. For example, some people indicate the difference between the Eucharist and ordinary food by matching pictures, or by sign language. Others simply by a quiet, reverent manner, or gesture. In fact, part of the reason the age for receiving Holy Communion was lowered was because of a little girl, 4 years old, who recognized in the Eucharist her beloved "Holy God," and expressed reverence, as well as a firm desire to receive Him. This is what is asked of all people who wish to receive Holy Communion.
Baptism is probably the most straight-forward. Basically if a person freely asks for it, is properly disposed, and is not legally prohibited, the only reason the Bishops give to defer is if "there is no reason for hoping that the person will be brought up in the Catholic religion". Further, "Disability itself is never a reason for deferring baptism. Persons who lack the use of reason are to be baptized provided at least one parent or guardian consents to it" (page 8-9).
This is what the bishops tell us about Confirmation: "All baptised, unconfirmed Catholics who possess the use of reason may receive the sacrament of Confirmation if they are suitably instructed, properly disposed, and able to renew their baptismal promises." This, and also if a person to be baptized is of a teachable age, is where developmentally appropriate catechesis, and adaptation comes in, and there are several choices as far a programs that can be used as well.
There is even provision for if a person will never attain the use of their reason "
Persons who because of developmental or mental disabilities may never attain the use of reason are to be encouraged either directly or, if necessary, through their parents to receive the sacrament of Confirmation at the appropriate time" (pg 11) [emphasis added]. One of the most joyous confirmation Masses I ever attended was that of a young man with Down Syndrome. He was so quiet during the rite, and then finally afterward he just couldn't contain it anymore, and gave a huge smile, and a cheer.
When it comes to reconciliation, obviously to commit a serious or mortal sin, a person must have use of his or her reason. That said, even young children, and people with mental disabilities are often aware of doing things they know to be wrong, and experience a sense of guilt and sorrow. The bishops tell us "as long as the individual is capable of having some sense of contrition for having committed sin, even if he or she cannot describe the sin precisely in words, the person may receive sacramental absolution." And further, "those with profound mental disabilities, who cannot experience even minimal contrition, may be invited to participate in penitential services with the rest of the community to the extent of their ability."
It is not my intention to address all the sacraments here, but more to illustrate the different forms that "positive disposition" and "intention" can take, and how the sacraments can be supported for those who have special needs.
