1- Why are men given Holy Communion before women?
Simply because women are more humble than men! So
I ask you to please stay humble and accept this regulation. Out of humility we do not think about who is first, but we prefer who is last.
2- Is the Holy Communion 100% Body and Blood of Christ? And if it is, why can't we see it as such?
If you saw blood would you drink it? And if you saw flesh would you eat it? It is very difficult and that's why the Lord hides this and gives us the spiritual blessing without us seeing it physically.
