Waving Bye Bye to God, 1933:
On April 20, 1939, Archbishop Orsenigo celebrated Hitler's birthday. The celebrations, initiated by Pacelli (Pope Pius XII) became a tradition. Each April 20, Cardinal Bertram of Berlin was to send "warmest congratulations to the Fuhrer in the name of the bishops and the dioceses in Germany" and added with "fervent prayers which the Catholics of Germany are sending to heaven on their altars."
Cardinal Secretary of State, Eugenio Pacelli (later to become Pope Pius XII) signs the Concordat between Nazi Germany and the Vatican at a formal ceremony in Rome on 20 July 1933. Nazi Vice-Chancellor Franz von Papen sits at the left, Pacelli in the middle, and Rudolf Buttmann sits at the right.
The Concordat effectively legitimized Hitler and the Nazi government to the eyes of Catholicism, Christianity, and the world.
It contained a "Secret Supplement" which shows, six years before the start of WWII, that General Mobilisation was only a matter of time and that the Catholic Church was "up for it".
In case of a change in the present German armed forces in the sense of the introduction of universal conscription, the induction of priests and other members of the regular clergy and the orders into military service will, with the understanding of the Holy See, be arranged within the framework of approximately the following guiding ideas:
a) Students of philosophy and theology at Church institutions who are preparing themselves for the priesthood are to be freed from military service and the preparatory drills for it, except in the case of a general mobilisation.
b) In the case of a general mobilization clerics who are employed in the diocese administration or the military chaplaincy are freed from reporting for duty. This applies to ordinaries, members of the ordinariate, provosts of seminaries and Church residences for seminarians, professors at the seminaries, parish priests, curates, rectors, coadjucators and the clerics who provide a church with worship services on a continuing basis.
c) The remaining clerics, insofar as they are considered suitable, are to join the armed forces of the state in order to devote themselves to pastoral care for the troops under the Church jurisdiction of the military bishops, if they are not inducted into the medical unit.
d) The remaining clergy in sacris or members of orders, who are not yet priests are to be assigned to the medical unit. The same shall apply when possible to the candidates for the priesthood mentioned in a) who have not yet taken their final vows.
