Imagine if Christians had the boldness to do such public displays of faith. I long for that day. Eucharistic processions followed by a parade thousands strong on every major feast day? Sign me up!

Now that I think of it, why donβt we do that? Have we all got too comfortable?
Leadership, or the lack thereof. I think we would have good participation if the priests and bishops would organize it, but we have fewer priests than we need and we continue to hemorrhage members to secularism our some sort of Protestantism.

Yep. Those hypocrites made their works public so to boast in them. I don't see how this relates to Eucharistic processions, which are fundamentally a humble undertaking, being that we boast not in our own works but in those of Christ and do so publicly.
Had to look up what a Eucharistic procession is- what verse of the Bible can I find that discusses them?
There is none. The gospels and and epistles were written during the life of Christ and during great persecution of Christians. Eucharistic processions would only become a practice after the Church became much less vulnerable.
