Over the last couple of weeks, Pope Francis hoisted himself up on sore legs dozens of times. As he crisscrossed large swaths of the Asia Pacific region, he shuffled from cars to his wheelchair, from the wheelchair to makeshift papal thrones and on and off many planes as hot, tropical winds blew on the tarmac.

The trip amounted to the longest and farthest reaching yet for Francis, and at 87, some of his supporters fear it may be one of his last. But that he flew thousands of miles to Asian countries with relatively small Catholic populations, braving oppressive temperatures and high levels of humidity and pollution, underlined Francis’s commitment to building a church with a less Eurocentric future.

“The long distance, the fatigue, the challenges,” said Cardinal Michael Czerny, a close aide to Francis. “They are part of the message.”

Francis’ papacy has from the start been one of symbols: the small modest cars he’s used, kissing the feet of criminals, the Casio watch he wears. His destinations are as much a part of his teachings as his homilies, and this trip to Indonesia, Papua New Guinea, East Timor and Singapore was seen as part of how he has defined his papacy.

The purpose, he has long made clear, is to emphasize outreach and inclusivity. As he visited remote, tropical villages in Papua New Guinea, he put in practice his pledge to embrace what he calls the church’s “peripheries,” faraway, minority or poorer Catholics.
