If Moses could go to the tabernacle of the Lord to adore Him, I think I might do the same, especially as the former is but a figure and foreshadowing of the Lord's Eucharistic Presence with us.
If the Jews could aodre His presence in the tent of His glory, or in the Ark, as the Hebrews did, then one can all the more adore Christ's Eucharistic Presence in His sanctuary. This is especially apt since the Ark, the Tent, the Sanctuary of the OT are just types and figures of His greater, future presence in the tabernacles of His future Church.
Mary's sinlessness is not a doctrine based on "silence." The Archangel Gabriel was not "silent" when he addressed her with the noble title "Kecharitomene" and said she was "Blessed" and "full of Grace." Being full of grace is the opposite of being full of sin.
"You end up arguing that “God could have done whatever He wanted, so since we want it, it must be true.â€
Where'd you get that? I didn't say that.
All the best!
All those words and not a single verse that teaches or commands EA.
Mary was full blessed with God’s choice of His Bestowed grace. That doesn’t mean, nor teach sinlessness. Indeed she stood in need of a Savior. Christ died for all mankind, including dear Mary.
Best to you always.
