To makeI've never made spiritual uplift a math class spiritually upliftinggoal of my teaching, teach somebut if asked, I would do it using history of the spiritual connections of math.
Discuss Newton's General Scholium to the Principia, his greatest application of calculus: "This most beautiful System of the Sun, Planets, and Comets, could only proceed from the counsel and dominion of an intelligent and powerful being."
Discuss Berkeley's Analyst, with its criticism of the unrigorous calculus and frequent comparisons to religion.
Discuss magic squares in a linear algebra class, perhaps reformulating the conditions in terms of matrices.
This has the advantage of connecting spirituality to particular topics in the math classes.
