Vobbe was ordained a priest on 14 June 1972; he married and has two sons. After serving as a chaplain (Kaplan) for five years in Catholic parishes in Cologne (1972–1974) and Düsseldorf (1974–1977), he joined the Old Catholic Church in 1977, becoming rector in Blumberg until 1982.

In 1994, the 52nd Ordinary Diocesan Synod elected him to become their ninth diocesan bishop, succeeding Sigisbert Kraft. He was consecrated a bishop on 24 March 1995, serving as the Bishop of the Old Catholics in Germany (based in Bonn) until 2009. As bishop of a church in full communion with the Church of England, he has been licensed as an honorary assistant bishop in that church's Diocese in Europe since 1999.
