Who they were
János Brenner was born at Szombathely, Hungary, on 27 December 1931 into a deeply Catholic family. A Cistercian novice from 1950, when the order was suppressed he continued his novitiate and studies in secret, and later became a diocesan priest.
After only two and a half years of ministry, on the night of 15 December 1957 he was lured from the presbytery at Rábakethely with a false call to bring Viaticum to a dying man and stabbed thirty-two times. When his body was found, he was still clutching the pyx with the Eucharist. He is called 'the Hungarian Tarcisius'.
The miracles
As a martyr, beatified without a miracle.
Why that counted as sanctity
A young priest killed on his way to a sick call, still holding the Blessed Sacrament.
