Speaking with the “Rio Negro” portal, the young priest acknowledged that his vocation “was born in the missions and among the sick” and that “it’s a gift, a gift from God.”
“One simply has to open up to that grace, to be available,” he said.
Born in the city of Catriel, at age 7 he began to attend Missionary Childhood (a worldwide organization of Catholic youth) in a poor neighborhood of his town.
That experience — as well as meeting a nun named Nieves — made an impact on his life. He was just a boy when he began to “know Jesus and call him a friend,” Oser recounted.
The call to a vocation began to take shape when at age 15 he visited a terminally ill patient with leukemia at a hospital in the city of Cinco Saltos along with a parish priest who, accompanied by a seminarian, was administering the sacrament of anointing of the sick to the patients.
At that time, Oser felt that science and medicine were not enough to end people’s suffering.
