The answer is: Titus

...Timothy... Titus... PHILEMON... Hebrews.

In the New Testament, the Order of the books can seem a bit puzzling at times. Right before Philemon is the brief yet impactful letter to Titus. It’s interesting to know that Philemon is one of the only letters penned solely for one person. Most epistles (writings) were directed to congregations or groups. It demonstrates a more personal nature of communication, akin to receiving a heartfelt letter from a friend.

In Titus, the Apostle Paul gives practical advice to suggest how to lead churches in Crete, while Philemon addresses the sensitive situation of a runaway slave, Onesimus, who became a Christian and sought reconciliation with his master, Philemon. The depth of personal relationships in the letter showcases dynamic human interactions, transcending fundamental societal norms rooted in the culture of the time.

Moreover, it’s intriguing to see how the letter of Philemon provides early evidence of new perspectives on social hierarchies. Paul steadily promoted the idea of equality among believers—“In Christ, there is neither slave nor free” (Galatians 3:28). Fun tidbit? Philemon is often regarded by scholars as one of the earliest examples revealing the seeds of abolitionist thought.

So read between the lines of these letters, and you'll not only learn about church policies and Greek culture but also about humanity and love transcending difficult situations—a beautiful invitation to rethink relationships even today!
