Perms, and catechism. No, Gretchen and Katie are not going through middle school again, they are walking through the Apostle's Creed in Luther's Small Catechism.
They talk about returning to school, kids growing up, aging, getting perms, midlife crisis', assessing your life, and then the creed--and how the creed is a steady truth that means more and more to them each year.
With catechisms in hand from both the CLB and the LCMS churches, where Gretchen and Katie each go, they compare how they are the same, and how each synod makes the catechism their own.
They briefly discuss the 3 different creeds, and the focus of teaching who God is, and why we confess them. The doctrine of who God is, is so unseparable from the gospel, as these 2 teachings go hand in hand.
Starting with the 1st article of the Apostle's Creed, Gretchen and Katie start with the explanation of God the Father.
