Conférence épiscopale allemande
In the negotiations to conclude the Reich concordat between Germany and the Holy See, even the German Bishops' Conference was kept at arm's length until shortly before the accord, but Gröber was provided preparatory information for the negotiations through his friend, Centre Party president Msgr. Ludwig Kaas; he eagerly promoted the process and thereby isolated himself from his fellow bishops. On 3 June 1933 a joint pastoral letter appeared from the German Bishops' Conference, the drafting of which the bishops had entrusted to Gröber. It contained a statement that if the State would only respect certain rights and requirements of the Church, the Church would gratefully and happily support the new situation.
