Early life
John Shanahan was born in Silver Lake, Pennsylvania, to John and Margaret (née Donovan) Shanahan, who immigrated to the United States from County Cork, Ireland. He studied at St. Charles Borromeo Seminary in Philadelphia.

Shanahan was ordained to the priesthood for the Archdiocese of Philadelphia by his brother, Bishop Jeremiah F. Shanahan, on January 2, 1869. He served as superintendent of Catholic schools in the archdiocese.

His brother Jeremiah was the first to hold that office, serving between 1868 and his death in 1886.

During his 16-year-long tenure, Shanahan erected 27 new parishes and increased the number of priests from 74 to 120. He opened an orphanage for girls at Sylvan Heights and a protectory for boys at Abbottstown, Pennsylvania, and completed construction on the Cathedral of St. Patrick in 1907. In 1907 he founded the Sisters of Saint Casimir.
