Can moral teaching develop over time?

This question sits at the heart of how different religious traditions understand truth.

This clip explores a key distinction:

Some traditions emphasise an unchanging application of revealed teaching.
Others—particularly within Catholic thought—speak of a development of doctrine.

Not a change in truth,
but a deeper understanding of it.

As Cardinal Newman famously argued,
truth unfolds as it is contemplated, lived, and understood across time.

Which raises a profound implication:

Practices once tolerated can later be clearly seen as incompatible with the deeper principles already present—such as the call to universal charity and human dignity.

So the real question becomes:

Is moral understanding static…
or can it grow as we come to grasp its full meaning?
