[5] During the summer of 1924 Beckmann transferred to Göttingen, where he became "Inspector of the Protestant College" ("Inspektor des reformierten Studienhauses") and, during 1924/25, completed his "Vikariat" (formal ministerial traineeship).

[b] Despite being held in wide regard among colleagues, and notwithstanding his teaching work at the university, Karl Barth never received an "ordinary" full professorship at Göttingen, possibly on account of his Swiss provenance, and was accordingly not authorised to supervise doctorates there.

[1] On 1 August 1926 it was through the hands of his own father that he was ordained into the ministry at the "Johanneskirche" (St John's Evangelical Church) in Wanne-Eickel.

[5][c] In January 1927 Joachim Beckmann married Hilde Hagemann: the marriage was followed in due course by the births of the couple's four children.

[5] In 1933 Beckmann took over a pastoral post with the Lutheran church community in Düsseldorf, retaining this ministry, by some criteria, without a break till 1948.

They had been banned under the terms of a decree issued by Reichsführer Heinrich Himmler on 29 August 1937, which prohibited any theological training by the Confessing Church.

[15] In 1947 he was elected deputy president of the National Brothers' Council ("Reichsbruderrat" or "synod") of the Evangelical Church, serving a two-year term till 1949, under the leadership of Heinrich Held.

[2] Following the organisational changes of 1949 Beckmann continued to serve as deputy to Praeses Heinrich Held till the latter's sudden death in 1957.

By the time he joined the synod, he had already been working directly under its mandate for three years, co-opted in 1964 to deal with the important issues involving Conscientious objectors on an on-going basis.

[5][12] In 1961 Beckmann was a co-signatory of the "Tübingen Memorandum", an open "manifesto", signed by eight high-profile protestant scholars and scientists, on the subject of West German nuclear re-armament, also calling for recognition by the West German government of the Oder–Neisse line as a permanent border between (East) Germany and Poland.

The memorandum gained extensive press coverage, backed by the fact that individual copies were sent to leading politicians including Richard von Weizsäcker, whose brother was one of the eight signatories.

Despite his involvement in the "Tübingen Memorandum", Präses Beckmann was generally to be found resisting pressure from younger church leaders to involve the church more intensively and more openly in the secular issues of the time, such as the heated passions, especially among politicised students, surrounding Cold War and Vietnam War.
