Whether the priest ought to deny the body of Christ to the sinner seeking it?

Objections

Objection 1 : It seems that the priest should deny the body of Christ to the sinner seeking it. For Christ's precept is not to be set aside for the sake of avoiding scandal or on account of infamy to anyone. But (Mt. 7:6) our Lord gave this command: "Give not that which is holy to dogs." Now it is especially casting holy things to dogs to give this sacrament to sinners. Therefore, neither on account of avoiding scandal or infamy should this sacrament be administered to the sinner who asks for it.
Objection 2 : Further, one must choose the lesser of two evils. But it seems to be the lesser evil if the sinner incur infamy; or if an unconsecrated host be given to him; than for him to sin mortally by receiving the body of Christ. Consequently, it seems that the course to be adopted is either that the sinner seeking the body of Christ be exposed to infamy, or that an unconsecrated host be given to him.
Objection 3 : Further, the body of Christ is sometimes given to those suspected of crime in order to put them to proof. Because we read in the Decretals: "It often happens that thefts are perpetrated in monasteries of monks; wherefore we command that when the brethren have to exonerate themselves of such acts, that the abbot shall celebrate Mass, or someone else deputed by him, in the presence of the community; and so, when the Mass is over, all shall communicate under these words: 'May the body of Christ prove thee today.'" And further on: "If any evil deed be imputed to a bishop or priest, for each charge he must say Mass and communicate, and show that he is innocent of each act imputed." But secret sinners must not be disclosed, for, once the blush of shame is set aside, they will indulge the more in sin, as Augustine says (De Verbis. Dom.; cf. Serm. lxxxii). Consequently, Christ's body is not to be given to occult sinners, even if they ask for it.
