Youth and ordination

Johannes Willebrands was born in Bovenkarspel, as the eldest of the nine children of Herman and Afra (née Kok) Willebrands. His father worked as a paymaster at the local vegetable market, and one of his brothers went on to become a Redemptorist missionary in Surinam. Willebrands studied at the Major Seminary, Warmond, near Leiden, where he was ordained to the priesthood on 26 May 1934. In 1937 he received a Doctorate in Philosophy at the Pontifical Athenaeum Angelicum in Rome with a thesis entitled John Henry Cardinal Newman Zijn denkleer en haar toepassing op de kennis van God door het geweten.

Early involvement in ecumenism

Willebrands returned to the Netherlands in 1937 and acted as chaplain of the Church of Begijnhof in Amsterdam. In 1940 he began teaching philosophy at his alma mater of the Warmond seminary. Five years later, he became the seminary's rector. Willebrands demonstrated a very active interest in the cause of Christian unity as president of the St Willibrord Association, which promoted ecumenism in the Netherlands; in 1951, he organized the Catholic Conference on Ecumenical Questions, which was in contact with the World Council of Churches.

Bishop of Mauriana

He was named Titular Bishop of Mauriana on 4 June 1964. Willebrands received his episcopal consecration on the following 28 June from Pope Paul VI, with Archbishops Diego Venini and Ettore Cunial serving as co-consecrators, in St. Peter's Basilica. On 7 December 1965, he read out the declaration by which the Catholic and Orthodox churches "cancelled out of the memory of men" their mutual excommunication following the Great Schism of 1054.

Pontifical Council for Promoting Christian Unity

On 28 June 1960, Pope John XXIII nominated him Secretary of the newly established Secretariat for Promoting Christian Unity (later elevated to a pontifical council), under the direction of Augustin Bea. Aided by fluency in six languages, Willebrands was involved in building bridges to the Anglican church, and the Russian Orthodox church.

He was instrumental in persuading the Orthodox churches to attend the sessions of the Second Vatican Council as observers while it met from 1962 to 1965.^[2][3] During the work of the Second Vatican Council, he prepared the documents relating to scripture and tradition, ecumenism, religious freedom, and relations with non-Christian religions. Willebrands was raised to the rank of Monsignor in 1963. On 12 April 1969, Pope Paul VI named Willebrands as President of the Secretariat for Promoting Christian Unity, succeeding Cardinal Bea after his death.

After his resignation as archbishop of Utrecht, Willebrands continued as president for Promoting Christian Unity. Willebrands acted as President Delegate at the Second Extraordinary Assembly of World Synod of Bishops, held from 24 November to 8 December 1985, and became President emeritus of the Pontifical Council for Promoting Christian Unity on 12 December 1989, when was succeeded as president by Edward Idris Cassidy.

Archbishop of Utrecht

On 6 December 1975, he was appointed Archbishop of Utrecht and thus de facto Primate of the Netherlands, continuing at the same time to serve as President of the Secretariat. It was hoped that would be able to use his diplomatic talents to reconcile the conservative and liberal wings of the Catholic Church in the Netherlands,^[4] but the qualities of patience, reticence and reservation that made him such a success in ecumenical circles did not endear him to his Dutch flock. He resigned as Archbishop on 3 December 1983.

Cardinal elector

He was created Cardinal-Deacon of Santi Cosma e Damiano by Paul VI in the consistory of 28 April 1969, and later became Cardinal-Priest of S. Sebastiano alle Catacombe on 6 December 1975.

Cardinal Willebrands was one of the cardinal electors who participated at the conclaves of August and October 1978, which selected Pope John Paul I and Pope John Paul II, respectively. During the latter conclave, the highly papabile Dutch prelate willingly withdrew his candidacy in order for Karol Wojtyła to be elected pope.^[5]

He became Camerlengo of the Sacred College of Cardinals in 1988, and served until 1995, after which the post was abolished.^[6]

Retirement and death

Cardinal Willebrands moved to the Franciscan convent of Saint Nicolaasstichting at Denekamp in 1997, where he died nine years later, at age 96. At the time of his death, he was the oldest living member of the College of Cardinals.
