Answer:
The act of repeating a message and explaining it in greater depth is Catechesis.
Step-by-step explanation:
Catechesis is a clear example of how a message, or simple words are taken and transmitted in a deeper way and with a background meaning.
If we take the example of a bible, what is done in a church is to read or repeat a fragment of it, and then explain its true meaning in a more thorough way.
Thus achieving a deeper message than what is really written.
