While attending Lindy and Miguel's wedding, Lindy's brother, Luke, ascertained some key information about how the religious dynamic between the new couple could play out going forward.

One of the first things that Luke did upon meeting Miguel was quiz him about his belief in God.

For context, Lindy and her family are all members of the Seventh-day Adventist faith, as revealed on the show. Per Wikipedia, Seventh-day Adventist practitioners are an offshoot of the Adventist Protestant Christian Denomination. Two of their key differentiating factors from other Christian-based faiths is that they recognize Saturday, not Sunday, as the Sabbath, and they put emphasis on an imminent second coming (often referred to as an advent) of Jesus Christ.

Although Lindy has explained in passing that she has moved away from the strict observance of the faith that her family practices, it still seemingly plays a huge role in her home life.

When Luke quizzed Miguel, who has a Ph.D. in neuroscience, he stated that "organized religious doesn’t quite make sense" to him.

This seemingly raised some red flags to Luke, who brought up the Bible to Miguel yet again in a following episode, this time in relation to sex. Still seemingly unconvinced of Miguel's moral standing, Luke notes, "Miguel is 35, to not have married at that point, there may be something not addressed yet."
