St. Patrick's Cathedral and evangelization

This year I again was a volunteer guide to explain the meaning of the nativity scene of St. Patrick's Cathedral with the Franciscan friars and sisters of the Renewal.

There were many ordinary questions but the memorable one came from a young boy who asked is sort of a repetition -- "Is this God's house?", "Where is God?", "Where can I see him?". I have answered this question in another form from adults, but I have about 30 seconds to explain it to an 8-year old:

God is everywhere so the whole universe is God's house.

In a special way, God is here in the cathedral, the whole cathedral is pictures of God and God's holy people.

Inside the cathedral, there's a special place where God is. It's called a tabernacle, it's a gold box next to a big candle to tell us God is inside.

Jesus held up bread and said "This is my body" -- changing the bread into his body. When the priest here does that, some of the people eat the body of Christ and some goes back into the tabernacle, the gold box, and people pray to Jesus before it.

His mother understood and hopefully in her own way she can help him understand.
