The crystal clear object

“Ding dong,ding dong”.
The church bells rang.
We all headed inside.
To find the altar back.
To find it.

He had read the
First reading.
Then the second.
He had blessed
the bread and wine

I saw a line
near the altar.
The priest called
me up.
Blessed with holy water.

I ate the Eucharist.
After that,my
Mum gave me
A clear rectangular prism
With bread and wine within.
