On November 12 the Most Rev. Helmut Dieser was installed as the VI Bishop of Aachen, Germany. His coat of arms is:

The description (translated from the diocesan website) is:

The coat of arms of the new bishop of Aachen shows two motifs in the shield: the one stands for the diocese of Aachen, and the other identifies the person of the bishop.The Diocese of Aachen has a black cross on a golden ground in the shield. In the smaller Mittelschild, the person of Bishop Dr. Helmut is designated.

The middle shield shows a silver dove against a red background with a green olive branch in its beak. The new bishop accepted this motif from his former coat of arms as an auxiliary bishop in Trier. It symbolizes his episcopal motto from the Philippine letter: “The peace of God exceeds all understanding“. The two colors red and silver also recall his origin from the diocese of Trier, which is a red cross in front of a silver ground in the shield. The dove with the olive branch is used in Christian art as a symbol of the new peace that God wants to bring to all his creation. This goes back to the biblical narrative of Noah and the great flood in the Book of Genesis. When finally the water no longer rises and gradually begins to flow away, Noach lets a dove fly from the ark several times. The second time she comes back with a fresh olive branch in the beak (Gen 8, 9-11). Noah understands: God does not want to spoil the earth, but makes it back to the homeland for life. God creates a new peace, which Noah and his own may accept in faith.

Peace, which surpasses all understanding, and which the whole of creation longingly waits for (see Romans 8: 21-22), arises from the greatest love of God, in which he gives his Son, so that all may come to the new life. The embellishments surrounding the coat-of-arms signify its bearer as a bishop: the green hat with six green tassels on each side, and the gold episcopal cross.
