This post by Michael Kruger provides an excellent example of how cultural context ought to inform both interpretation and application. The New Testament repeatedly commands Christians to show hospitality. Unless we understand what that meant to the original readers, we will miss much of the purpose of the command today.

Harnack also highlights the extensive travel of later Christian leaders such as Justin, Hegesippus, Julius Africanus, and (especially) Origen.

Origen travelled to Sidon, Tyre, Bostra, Antioch, Casesarea, Nikomedia, Athens, Nicopolis, Rome, and number of other cities (some of which he visited more than once). Such travel was made possible because of the advancements made in the first-century Roman roads, though journeys were still slow and often dangerous.

But, Christians didn’t just travel for missionary work. They traveled for two additional reasons. First, travel was the way they spread Christian writings in the ancient world. It wasn’t just a generic message that these missionary-teachers were promulgating, but particularly Christian texts. Even in the first century, we see that early Christians had a remarkably well-organized network for distributing their writings. For instance, Paul frequently names the letter-carriers who would often have to travel great distances to deliver his epistles.

Second, and equally important, Christians traveled for the purposes of fellowship, networking, and encouraging one another. Despite the lack of modern travel conveniences, Christians traveled great distances just to be with one another. They were so highly networked, that one recent writer referred to early Christians as having a “Holy Internet.”
