κουστωδίαν - Latin Custodia

The Javelin was bringing to light to themselves, "You are holding a custodia. Lead under, fortify, just as you have known/seen."

Custodia - Container of the Presence

A custodia is the receptacle used for the Eucharist, (called "blessed sacrament/literal presence"). The term "custodia" denotes the vessel or container used to hold the consecrated Host (the Eucharist). This includes the monstrance or ostensorium, where the Host is displayed for adoration.
