The other was dedicated in honour of St.James and St.John the Apostles.
The Sunday after the Feast of the Blessed Gallus the Abbot (which is in the month of October), was appointed to be kept in every year as the anniversary of the dedication of this church and the several altars therein; and on this day also is kept the Dedication Festival of the House of the Blessed Virgin in Windesem and of the Convent of Nuns at Diepenveen, to the glory and honour of the most Blessed Trinity.
In the same year, when their General Chapter was held at Windesem, the venerable Fathers of the Canons Regular in Brabant came thereto, and were accepted and united to our Fraternity, together with the Houses belonging to them.
In this year from the Feast of Pentecost onward the Canonical Hours were sung in our church after the monastic manner.
CHAPTER XV.
Of the death of the beloved Father John Ummen, the first Founder of the Monastery of Mount St.Agnes.
In the year 1420, in the evening of the 1st day of September, the Feast of St.AEgidius the Abbot, died that holy and faithful servant of Christ, John Reghelant, formerly a most beloved disciple of Gerard Groote, whose discourses he used to hear.

He was born of honest parents, and for several years was educated in Zwolle; but while he was yet a youth he was diseased in the eyes, and God allowed him to fall into darkness, and he continued blind to the end of his life; but yet the less he could see the outer world, the more brightly did the grace of God illumine him inwardly.

His mother, whose name was Regheland, was devoted to God, and often went on long journeys to visit the shrines of Saints in company with her blind son, whom she would lead by the hand, taking him with her to hear sermons in church, and leading him onward to every good thing.
So when the venerable Master, Gerard Groote, was preaching in Zwolle, and through God's inspiration was bringing compunction to many, the Lord did open the heart of this His servant also, and did inflame him, wherefore he began to love Gerard much, and often sought to be instructed by the doctrine of so great a man.

For this cause he left wandering about the world and sought to serve God in quietness, also he exhorted all that came to him to despise earthly desires, and take hold on that new life in Christ which Gerard taught by his holy manner of living.
Therefore he took to him certain men that were well disposed, and with them he began to live the Common Life in Zwolle, but afterward they took up their abode upon Mount Nemel (which is now called Mount St.Agnes), because they wished to dwell outside the tumult of the world.

Here they gathered a larger company, the which he governed for many years with faithful devotion, assisted by divers helpers, until the monastery was founded, for he did not fear the many hindrances that met him.
