Inspired by the figure of Maximilian Kolbe, he developed a relationship with the Order of Friars Minor Conventual in Louvain.

[3] Within his Franciscan order he has held various positions: vocational promoter, secretary, vicar and provincial minister of the Belgian province of the Friars Minor Conventual, serving as delegate general when the provinces of Belgium and France merged; rector of the national shrine of Saint Anthony of Padua in Brussels and director of its Confraternity.

He was also president of two non-profit organizations that support the Friars Minor Conventual in Belgium, and had responsibilities with the Catholic School of Landen.

He has served as president of the Central Europe Federation of the Friars Minor Conventual (Austria, Croatia, Denmark, Germany, Holland, Slovenia, Sweden, Switzerland) and was a member of the Franciscans' International Commission for the Economy.

[6] In March 2021 he told an interviewer that from the time he entered religious life he "almost always felt affinity with the Islamic world".
