MAUMERE, Indonesia — Arnoldus Yansen thought for certain he was going to become a Catholic priest, just like his older brother, cousin and uncle.
He attended St. Peter Major Seminary, a bastion of priestly vocations located in the middle of a jungle on Flores, a predominantly Catholic island in Muslim-majority Indonesia. Known familiarly as Ritapiret Seminary, St. Peter Major has produced 13 bishops, more than 580 diocesan priests and 23 deacons in nearly 70 years of existence.
But Yansen won't be among them. He tried to shake off what he thought were last-minute jitters before entering the priesthood. Instead, Yansen took off his clerical robes for good and joined the hundreds of prospective priests who resign or fail to take up Catholic vocations every year in Indonesia.
''I felt like I didn't fit in anymore and that I would be able to do more if I left,'' said Yansen, 26, who is now an administrator at a Catholic school, Ledalero Institute of Philosophy and Creative Technology.
Pope Francis' upcoming trip to Indonesia is putting a spotlight on the 8.6 million Catholics who make up 3% of the population. It's a country where religious minorities remain on edge due to militant attacks that have targeted faith groups.
More men are entering seminary, but Yansen and others like him show that Indonesia is not immune from trends contributing to the Catholic Church's global priest shortage, including fallout from the clergy sex abuse crisis and the pull of the fast-paced modern world.
''The number of priests is never enough,'' said the Rev. Guidelbertus Tanga, rector of St. Peter Major Seminary, which is considered the largest Catholic seminary in the world by enrollment.
In Indonesia, there 2,466 diocesan priests in Indonesia in 2022, up from 2,203 in 2017, according to Vatican statistics as of Dec. 31, 2022, the last year for which data is available. That number is supplemented by even more religious order priests, such as Jesuits or Franciscans, whose numbers reached 3,437 in 2022.
