“Jesus is capable of hiding His Glory. Was He recognized immediately on the road to Emmaus? No. It was”in the breaking of the bread.”
He had not yet ascended.
“The Monstrance is decorated in His Honor. “
It may be done to try to honor Him. I cannot judge the motive. The truth though is that Christ is exalted and glorified above every name that is named. The monstronce is an idol or attempted glory. A toy in comparison to His glory.
He is the Creator. We are the creation. Can anything we do compare to His Glory? It is He Who is in the Sacrament. We do our best to honor Him.
Luke 24 He had resurrected from the dead. No, not ascended. We won't see Him in His full glory until we're in Heaven, or He comes again, whichever is first.
