Jaweed Kaleem, the Religion Newswriters Association’s 2013 Supple Religion Feature Writer of the Year, produces exceptional journalism on a regular basis. Don’t be surprised if his latest story — in which he goes inside Pakistan to report on religious minorities — turns out to be one of the best religion news stories all year.

KARACHI, Pakistan — Every Sunday, thousands celebrate Mass at St. Peter’s, a three-floor, 21,000-square-foot Catholic church that’s the biggest in Pakistan. Dressed in their best tunics and loose cotton pants, worshippers sit barefoot in the pew-less building — a style adapted from nearby mosques — as they sing hymns to the sounds of drums and a piano. As the sun sets, a light shines in a 24-hour prayer room, something common in Western nations but a rarity here.

The success of St. Peter’s, which cost $3.8 million to build — making it the most expensive in the nation when it opened two years ago – has been hailed as a sign of progress for Christians and religious minorities. Yet beyond its bold size and growing attendance, the difficulties parishioners face stand out here as much as at any other non-Muslim house of worship in this overwhelmingly Islamic country. Guards are outside to protect worshippers from would-be suicide bombers and attackers. Prayers for recent Christian martyrs are said regularly during services. Priests use nonalcoholic wine or grape juice during Holy Communion, partly because it’s cheaper, but also to avoid inflaming Muslims who believe drinking is sinful.
