Question 4 - Receiving Holy Communion
Nobody should hesitate to wait before receiving Holy Communion when not sure if he is in the proper dispositions. The priest should be consulted in confession if there are doubts about whether or not Holy Communion should be received in such or such circumstances.
Parents should be very prudent in inquiring why one of their children did not receive Holy Communion. I suggest that parents start delicately inquiring of the reasons only if the abstention of Communion lasts too long. The same prudence and discretion should be kept between spouses.
Abstention from Holy Communion when needed, far from being shameful, only proves our Faith and veneration for such a holy Sacrament.
All that being said, one must also avoid :
becoming exceedingly scrupulous : this sacrament is not one of people who have reached holiness, but one of people who, although holy in the sense that they are in the state of grace, are in need of the grace of God to overcome their weaknesses.
taking the habit of staying in the state of mortal sin for long periods of time. This would be the highway to hell.
