Döllinger will go on to become a theologian and church historian, teaching ecclesiastical history and canon law in Aschaffenburg. He also becomes a primary reason for the establishment of the Old Catholic Church in Germany.
An outspoken opponent of papal infallibility, Ignaz von Döllinger's refusal to submit to the conclusions of the Vatican Council will create international support for him — including support from Old Catholic Church leaders in the Netherlands who are invited to Munich.
Ultimately, though, Ignaz von Döllinger won't support the Old Catholic movement to the point of being ordained a bishop by them and this causes the movement to lose a lot of steam. The Old Catholic Church still gets established, but the schism with the Vatican remains minor.
