The second wave of influenza in the fall of 1918 was the worst yet and, by the time Father Nicola Yanney reached Wichita, Kansas, a citywide quarantine was in effect.

A 16-year-old girl had already died, creating a sense of panic. The missionary priest -- his territory reached from Missouri to Colorado and from Oklahoma to North Dakota -- couldn't even hold her funeral in the city's new Orthodox sanctuary. As he traveled back to his home church in Kearney, Neb., he kept anointing the sick, hearing confessions and taking Holy Communion to those stricken by the infamous "Spanish flu."

After days of door-to-door ministry in the snow, Yanney collapsed and called his sons to his bedside. Struggling to breathe, he whispered: "Keep your hands and your heart clean." He was one of an estimated 50 million victims worldwide.

A century later, many Orthodox Christians in America -- especially those of Syrian and Lebanese descent -- believe Yanney should be recognized as a saint. And now, as churches face fears unleashed by the coronavirus, many details of his final days of his ministry are highly symbolic.

"Father Nicola got the flu because he insisted on ministering to people who had the flu," said Father Andrew Stephen Damick, creator of "The Equal of Martyrdom," an audio documentary about the man known as "The Apostle to the Plains."

"For priests, there are risks. But you cannot turn away when people are suffering and they need the sacraments of the church. You go to your people and minister to them. This is what priests do."

Few acts in ministry are as intimate as a priest huddled with a seriously ill believer, hearing what could be his or her final confession of sins.
