Whether the seminal loss that occurs during sleep hinders anyone from receiving this sacrament?

Objections

Objection 1 : It seems that seminal loss does not hinder anyone from receiving the body of Christ: because no one is prevented from receiving the body of Christ except on account of sin. But seminal loss happens without sin: for Augustine says (Gen. ad lit. xii) that "the same image that comes into the mind of a speaker may present itself to the mind of the sleeper, so that the latter be unable to distinguish the image from the reality, and is moved carnally and with the result that usually follows such motions; and there is as little sin in this as there is in speaking and therefore thinking about such things." Consequently these motions do not prevent one from receiving this sacrament.
Objection 2 : Further, Gregory says in a Letter to Augustine, Bishop of the English (Regist. xi): "Those who pay the debt of marriage not from lust, but from desire to have children, should be left to their own judgment, as to whether they should enter the church and receive the mystery of our Lord's body, after such intercourse: because they ought not to be forbidden from receiving it, since they have passed through the fire unscorched."From this it is evident that seminal loss even of one awake, if it be without sin, is no hindrance to receiving the body of Christ. Consequently, much less is it in the case of one asleep.
Objection 3 : Further, these movements of the flesh seem to bring with them only bodily uncleanness. But there are other bodily defilements which according to the Law forbade entrance into the holy places, yet which under the New Law do not prevent receiving this sacrament: as, for instance, in the case of a woman after child-birth, or in her periods, or suffering from issue of blood, as Gregory writes to Augustine, Bishop of the English (Regist. xi). Therefore it seems that neither do these movements of the flesh hinder a man from receiving this sacrament.
Objection 4 : Further, venial sin is no hindrance to receiving the sacrament, nor is mortal sin after repentance. But even supposing that seminal loss arises from some foregoing sin, whether of intemperance, or of bad thoughts, for the most part such sin is venial; and if occasionally it be mortal, a man may repent of it by morning and confess it. Consequently, it seems that he ought not to be prevented from receiving this sacrament.
Objection 5 : Further, a sin against the Fifth Commandment is greater than a sin against the Sixth. But if a man dream that he has broken the Fifth or Seventh or any other Commandment, he is not on that account debarred from receiving this sacrament. Therefore it seems that much less should he be debarred through defilement resulting from a dream against the Sixth Commandment.
