Arthur BOSSCHAERTS, founder of the Vita & Pax Foundation and Abbot commissioner, was born in Antwerp on 20 June 1889 and died in Schotenhof on 3 March 1950, and was burried on 7 March 1950, at the age of 60 years old, as the son of Constantinus Joannes and Joanna DE WORM.

Constantinus was a Flemish Benedictine and a leader concerning the work of reunification and the liturgical movement. In 1908 he entered the abbey of Affligem as a Benedictine. From there, he was sent in 1922 to the abbey of Ramsgate and he became the rector of a Abbey of Benedictine Nuns in Eccleshall, with the intention to revive this community.
Pope Pius IX asked, on advise of the Oekrain metropolitan Sceptyckyj, the Benedictines to start the reunification of the churches. In 1925 was Constantinus invited to come to Rome. In the same year he accompanied Mgr. Roncalli (the later pope Johannes XXIII) as a secretary on a visit-trip to Bulgary, what offered him the opportunity to learn the oriental christianity and the Slavic tradition. In 1926 in Belgium two Benedictine Abbeys were founded for the reunification, one in the Walloon territory (in Amay-sur-Meuse, now in Chevetogne) and one in the Flemish territory, where Schotenhof was selected. Cardinal Van Roey judged that only one establishment was enough, so after three years the small community of Schoten was closed.
Constantinus, at that time the prior of Schotenhof, was full of dynamism and initiative power. He started the institution of 'internal' oblates: laymen who devote themselves to the apostolate of the world, but remain under the agreements of a Benedictine Abbey, where they share the life of the community. In order to realize this daring plan, he asked at the sisters of Eccleshall to establish themselves in Schotenshof. They agreed, and so arose in 1926 the priory of Regina Pacis of the Benedictine Nuns in Schotenhof.

The community of Benedictine Nuns had her origin at the beginning of the 19th century, when Marie Chevalier founded a monastery community in Rouen for women under the rule of St. Benedict. From this grew the priory of the Benedictine Nuns of the Immaculate Conception, that in 1892 was affiliated with the congregation of Monte Oliveto. As a consequence of the laws of Combes, in 1901, the sisters had to move from Eccleshall to Bicester in England.
The congregation of Monte Oliveto was founded in the 14th century by the blessed Bernardus Ptolemeus of Siena, who followed the Rule of the Benedictines. The congregation was characterized by a more organic than a federative structure. It had a greater dependence of the main abbey of Oliveto.
The monials had tasks in pastoral, apostolic and social work, but they maintained an authentic monastique lifestyle. The priory of Schoten was first located in the court Ter Donk, but later they moved to the domain of Schotenhof.
Constantinus gave them the motto 'Vita et Pax' to give a new impulse to the ideal of peace and unity of the Benedictines.

On 25 March 1933 Constantinus joined the white dressed Benedictines of Monte Oliveto. The priory was already affiliated. Schotenhof was renamed as the congregation of Sancta Mariae Montis Oliveti. Moniales, also monastique formed laymen, and oblates were permitted for the apostolate in the world. The oblates as well as the monials knew a success, what led to a rising number of vocations (until 35 monials).
In Schotenhof, Constantinus founded new Vita et Pax monasteries in London and Rochester (1936), Ribeirao Preto in Brasil, Fiesole near Florence (1936) and a house of Byzantine ritus in Le Cateau in North France (now in Moustier-en-Fagne near Trélon). Through Constantinus, the entire order was applied to the work of the reunification.
In 1946 Constantinus was consacrated as an Abbot. In that year he also founded in Louvain a Vita et Pax center of Byzantine rite to give young monks a special education for the reunification work.
Shortly before his death Constantinus was dedicated by the congregation for Oriental Rites for the Liturgical Apostolate of the Oriental students of the university of Louvain.
Constantinus was a commander in the order of ‘Sancta Giorgio di Antiochia’.
