Ida (Dutch Ida) was born around 1211 at Louvain to a wealthy Brabantine merchant family — the unlikely bourgeois background for medieval sanctity. Her father was a Louvain merchant who suffered financial misfortune during Ida's youth, producing the family's financial ruin.
Ida undertook the active mystical-devotional life in her youth — in the Brabantine Beguine tradition of the early 13th century (the Brabantine Beguine movement was the principal women's-lay-religious movement of the 13th-century Low Countries, producing dozens of Brabantine women mystics).
Around 1234, at the age of 23, Ida entered the Cistercian Monastery of Roosendaal in Brabant — following the Brabantine Beguine-Cistercian pattern of women moving from the lay-Beguine to the monastic-Cistercian vocation.
Ida spent the 56 years (1234–1290) at Roosendaal, undergoing extensive mystical-ecstatic experiences that were documented in her Vita (composed shortly after her death). The Vita records: stigmata (receiving the marks of the Passion of Christ on her body — one of the earliest documented Catholic stigmatics, in institutional parallel with contemporary Franciscan stigmatics), Eucharistic-mystical experiences (receiving the sacred host without bodily eating), visions of Christ and the Blessed Virgin, levitations during prayer, and bilocations.
The Ida-of-Louvain Vita establishes the distinctive Brabantine Beguine-Cistercian mystical tradition of the 13th century — in institutional parallel with the contemporary lives of Sts. Marie of Oignies (1213), Christina the Astonishing (1224), Lutgardis of Aywières (1246), Beatrice of Nazareth (1268), Ida of Nivelles (1231), and Ida of Lewis (1300).
She died at Roosendaal on October 28, 1290.
