Fallacy?

During a conversation we were discussing the type of music that I enjoy. His reply, it's important to grow in your faith and become a mature Christian. You're not there yet, give it time.

Certainly! The response given in the conversation contains a logical fallacy known as a "non sequitur." A non sequitur occurs when a conclusion or statement does not logically follow from the previous argument or statement.

In this case, the original statement was about the type of music that you enjoy. The reply, however, shifts abruptly to the topic of growing in faith and becoming a mature Christian, implying that your musical preferences are somehow indicative of your spiritual maturity. This leap in reasoning is not logically connected to the initial conversation about music.

Additionally, this response could also be seen as containing an element of the "ad hominem" fallacy if it is interpreted as attacking your character (i.e., your level of faith or maturity) instead of addressing your point about music preferences.

In sum, the fallacies here are:
1. **Non Sequitur**: The conclusion about faith and maturity does not logically follow from the type of music you enjoy.
2. **Possible Ad Hominem**: If the statement is intended to undermine your argument by attacking your level of spiritual maturity rather than addressing the actual topic of music preferences.
