Bonnici, 56, has served as a priest of the Archdiocese of New York for 30 years.
He holds a doctorate from the Pontifical John Paul II Institute in Washington (1995) and a licentiate degree from the Pontifical John Paul II Institute (1992) in Rome, where he also studied at the Pontifical North American College and the Gregorian University (1987-1990) before his ordination.
Bonnici previously served as director of the archdiocese’s Respect Life Office for six years and as the pastor of St. Columba in Chester from 2008 to 2021.
He was born in New York on Feb. 17, 1965, and earned a Bachelor of Science degrees in biology and philosophy from St. John’s University in Queens, New York in 1987.
Bonnici’s most recent assignment was as pastor of St. Augustine parish and Saints John and Paul parish in Larchmont.
Bonnici and Espaillat’s episcopal ordinations will take place at St. Patrick’s Cathedral on March 1.
The Archdiocese of New York has a total population of 6.2 million, 2.81 million of whom are Catholic. Cardinal Timothy M. Dolan has served as the archbishop of New York since 2009.
"Pope Francis has selected two outstanding priests, both experienced pastors, to serve the people of God of this archdiocese as auxiliary bishops," Dolan said in a statement on the archdiocese's website.
"I look forward to working even more closely with Bishop-elect Bonnici and Bishop-elect Espaillat, as they undertake this new role in their priesthood."
With the addition of Bonnici and Espaillat, there will be a total of five active auxiliary bishops serving the Archdiocese of New York.
