Again, worthiness is between a man and his God, not between a man and his church.
“Who is he that judges another man’s servant? to his own master he stands or falls. Yes, he shall be held up: for God is able to make him stand” Rom 14:4.
Why are you making comments about a Catholic issue, when you know nothing about it?
Since we're discussing a Sacrament of the Catholic Church, where only a validly ordained priest of the church can consecrate bread and wine (not a lay person) into being the Body and Blood of Christ, the Church has full rights to decide who is eligible to receive Communion in order to not profane the Sacrament. By creating rules regarding reception, the Church does the best it can to prevent blasphemy and/or sacrilege from occurring. Since priests are the ones entrusted with the Body and Blood of Christ, everything regarding reception is under their, and the Church's, purview.
Without rules regarding reception, blasphemy and/or sacrilege would be more rampant than it is today.
