The SyroMalabar Knanaya Mission of Philadelphia started at St. Antony of Padova Church, Ampler, Pennsylvania in 1999, with Rev. Fr. Thomas Vattothuparambil as its director. He started Holy Mass for this community once in a month. When Fr. Vattothuparambil went back to Kottayam, Bishop Mar Jacob Angadiath appointed Fr. Jose Tharackal as the mission director from October 23, 2009. Monthly Holy Mass continued to celebrate at St. Albert the Great Church, Huntingdon Valley, Pennsylvania.
Later, when the Knanaya people of Philadelphia expressed their desire to have Mass in SyroMalabar rite every week, Bp. Mar Jacob Angadiath appointed Fr. Mathew Manakatt as the Mission director with effect from July 21, 2011. He was serving also as a parttime Parochial Vicar at St. Albert the Great Church. About 38 families are active members of this mission, coming regularly for Holy Mass. On November 1st 2011, the Feast of all Saints, with the approval of Mar Jacob Angadiath, the SyroMalabar Knanaya Catholic Mission of Philadelphia was renamed as St. John Neumann Knanaya Catholic Mission of Philadelphia. Thus the Knanaya Mission of Philadelphia is known after an American saint, St. John Neumann who was a former Bishop of the Archdiocese of Philadelphia.
Fr. Renny Abraham Kattel is the present mission director and he resides at Assumption Catholic Church, 1900 Meadowbrook Rd, Feasterville, PA 19053
