OK. In/at the Consecration, Jesus becomes Present - Body, Blood, Soul, and Divinity. As long as the accidents (the bread and wine) are superficially present (eg. nobody has ingested them and they have been dissolved) His Presence continues to be in those accidents, no matter how small the piece. After the Holy Communion, whatever accidents remain are placed in the Tabernacle (the beautiful box-like recepticle on the altar - sometimes with a curtain around it). A person can go into a parish church at any time (as long as the door is unlocked, that is), sit/kneel in the pew, and be with Him, there. Exposition is when the priest places a consecrated Wafer/Jesus in a monstrance (like these)
and a person can Adore Him visually, also. There is a brief liturgy associated with this (“Benediction”).
Well, I imagine I’ve made things as clear as mud.:eek: Maybe someone else will give it a try? Also, if you ask about this to Fr. Serpa in Ask an Apologist, I’m sure he’s answered this question a million times and might be clearer.
