Most parts of the liturgy are teaching. Scripture readings might compare with text book reading; the Lord's Prayer and other formulaic recitations are often taken from Scripture.

The eucharist is more "ritual" than "overt teaching" but it is meant to call to mind one loaf -> one body and the cost of forgiveness.

The earlier poster's point was more "with similar goals in mind" (i.e., "to create a shared understanding of the world, a nation") rather than emphasizing the mechanism (I think). "Marketable skills" is different from social/civic skills/responsibility.
