I found this to be helpful, from Doug Wilson:

A worldview is not just thoughts in your head, even if they are orthodox thoughts. A worldview consists of four major components—catechesis, narrative, symbols, and lifestyle.

Catechesis concerns how you answer the questions. Christian, what do you believe?

Narrative raises and answers the question, “Who are your people, and how did you get here?”

Symbols are the unspoken ways that we communicate who we are, and what our allegiances—baptism, cross necklaces, liturgies in worship, and so on.

Lifestyle has to do with the day-to-day stuff—eating habits, clothing, sexual mores, etc.

The first two elements of a worldview are propositional, and the last two are not.
