Hundreds of people have gathered to witness the beatification of a New Jersey nun credited with curing a boy's eye disease.

Sister Miriam Teresa Demjanovich is being beatified Saturday during a Mass, led by Cardinal Angelo Amato at the Cathedral Basilica of the Sacred Heart in Newark.

The Archdiocese of Newark says she is credited with curing a boy's macular degeneration in the 1960s, long after she died.

Michael Mencer was given a lock of her hair and prayed to her. Roman Catholic Church officials say the effects of the eye disease soon began to fade.

Pope Francis has pronounced it a miracle.

Mencer and Demjanovich family members were among those attending the Mass.

Beatification is the third of four steps toward sainthood.
