The episode of Navigating the Cross, "How to Take Your Faith Seriously," features host Spencer and guest Luke, the brother of a previous guest. Luke, described as a "pretty devout Catholic," discusses his journey to taking his faith more seriously, noting that he only started "living it out well" about two years ago, upon arriving at St. Leo.

The conversation centers on the hosts' mutual experiences of lukewarmness and lack of care for the faith during high school and middle school. They reflect on the poor catechesis they received, particularly concerning the seriousness of the Eucharist and the lack of teaching on topics like mortal sin (specifically that one cannot receive Communion while in a state of mortal sin) and the Church's sexual ethics. They contrast this with a discussion of the importance of both God's love and His justice.

Luke's conversion was inspired by upperclassmen and student ministry leaders, such as "J Paul" (who is now in seminary), serving as visible, holy role models. Key advice for college Catholics includes the bare minimum—attending weekly Mass, going to Confession, and establishing a routine of prayer—and the vital necessity of community and getting rid of pride. They conclude by stressing that faith formation primarily starts in the domestic church (the family).
