Gustaaf Joos (Sint-Niklaas 5 July 1923 – 2 November 2004) was a prelate of the Diocese of Ghent, who was elevated to the Roman Catholic College of Cardinals on 21 October 2003 by Pope John Paul II.
He studied with Karol Woytyla in the Belgian Pontifical College before the latter's election to Pope John Paul II. Before his nomination as cardinal he was made a member of the St Bavo Chapter in 1961.Canon Joos was a judicial vicar in ecclesiastical tribunals of the diocese of Ghent, doctor in canon law. He was professor at CIBI and the seminary.
In 2003 the Vatican published the wish of the pope to Create Joos Cardinal in the next Consistory. In Belgium everyone was surprised, in the Belgian media he was only known as a parish priest. Belgian media mistook him for another priest just after he was elevated to Cardinal. It was the first time in the history of the diocese that a canon was elevated to cardinal. His elevation as cardinal was seen by many as gratitude from Pope John Paul II towards his long-time friend.
After announcing his intention to elevate Canon Joos to the Cardinalate, Pope John Paul also appointed him as Titular Bishop of Ypres, and he was consecrated on 7 October 2003, days before the Consistory in which he was raised to the College of Cardinals. Joos was already 80 years old when he was elevated to cardinal and conform the motu Ingravescentem Ætatem he was not eligible to vote during future Conclaves. After his elevation, Cardinal Joos continued to live in the Diocese of Ghent, serving as a parish priest and as judicial vicar in ecclesiastical tribunals.
The cardinal died in Landskouter, and received a pontifical funeral in Saint-Bavo cathedral. He was buried like requested in Landskouter, and not in the Cathedral of Ghent.
Joos gained notoriety in January 2004, when in an interview to Belgian P-Magazine, he said, about homosexuals:
