Chapter 4: Holy Communion
1. Dispositions for the Reception of Holy Communion
[80.] The Eucharist is to be offered to the faithful, among other reasons, “as an antidote, by which we are freed from daily faults and preserved from mortal sins”, as is brought to light in various parts of the Mass. As for the Penitential Act placed at the beginning of Mass, it has the purpose of preparing all to be ready to celebrate the sacred mysteries;even so, “it lacks the efficacy of the Sacrament of Penance”, and cannot be regarded as a substitute for the Sacrament of Penance in remission of graver sins. Pastors of souls should take care to ensure diligent catechetical instruction, so that Christian doctrine is handed on to Christ’s faithful in this matter.
[81.] The Church’s custom shows that it is necessary for each person to examine himself at depth, and that anyone who is conscious of grave sin should not celebrate or receive the Body of the Lord without prior sacramental confession, except for grave reason when the possibility of confession is lacking; in this case he will remember that he is bound by the obligation of making an act of perfect contrition, which includes the intention to confess as soon as possible”.
[83.] It is certainly best that all who are participating in the celebration of Holy Mass with the necessary dispositions should receive Communion. Nevertheless, it sometimes happens that Christ’s faithful approach the altar as a group indiscriminately. It pertains to the Pastors prudently and firmly to correct such an abuse.
[84.] Furthermore when Holy Mass is celebrated for a large crowd - for example, in large cities - care should be taken lest out of ignorance non-Catholics or even non-Christians come forward for Holy Communion, without taking into account the Church’s Magisterium in matters pertaining to doctrine and discipline. It is the duty of Pastors at an opportune moment to inform those present of the authenticity and the discipline that are strictly to be observed.
[85.] Catholic ministers licitly administer the Sacraments only to the Catholic faithful, who likewise receive them licitly only from Catholic ministers, except for those situations for which provision is made in can. 844 §§ 2,3, and 4, and can. 861 § 2. In addition, the conditions comprising can. 844 § 4, from which no dispensation can be given, cannot be separated; thus, it is necessary that all of these conditions be present together.
[86.] The faithful should be led insistently to the practice whereby they approach the Sacrament of Penance outside the celebration of Mass, especially at the scheduled times, so that the Sacrament may be administered in a manner that is tranquil and truly beneficial to them, so as not to be prevented from active participation at Mass. Those who are accustomed to receiving Communion often or daily should be instructed that they should approach the Sacrament of Penance at appropriate intervals, in accordance with the condition of each.
