Bishop-designate Deliman has served on the archdiocese's metropolitan tribunal, in its youth ministry office, and on the diocesan presbyteral council. He was spiritual director at St. Charles Borromeo Seminary from 2001-2006, and priest vocation coordinator from 2005-2009.
Archbishop Chaput congratulated the bishop-designate and asked the people of the archdiocese to join him in praying "that the Holy Spirit will strengthen him as a successor to the apostles."
"We are all blessed to receive such a gift from the Holy Father in the person of Bishop-elect Deliman," the archbishop said.
He added that Pope Francis' choice of the new bishop continues a long Philadelphia tradition of priests being recognized for their ability to serve as bishops.
There are presently three auxiliary bishops in the archdiocese: Bishop Timothy Senior, the rector of St. Charles Borromeo Seminary; Bishop Michael Fitzgerald, who heads the office of Catholic education and five administrative offices; and Bishop John McIntyre, who is responsible for archdiocesan Catholic Human Services and evangelization ministries.
There are about 1.4 million Catholics in the Philadelphia archdiocese, among 4 million people.
Bishop-designate Deliman's future role is yet to be determined. However, Archbishop Chaput said he would visit all parishes in the archdiocese with Hispanic populations.
The bishop-designate thanked Archbishop Chaput for his support and guidance.
"This news was a complete and unexpected surprise to me and it's certainly been a lot to absorb," he said.
