Cornelis Anslo became a Waterlander preacher on 14 July 1617. Schijn calls him a very earnest, pious, upright and intelligent preacher. His wealth enabled him to give liberally to the poor. In 1625 he became involved in a violent dispute with a fellow preacher, Nittert Obbesz, and published against him the pamphlet, Dialogus of Zaamenspreekinge tusschen eenen waarheidszoekenden Neutralist genoemd Vrederik en een waterlandschen broeder (Hoorn, 1626). Among his friends were Joost van den Vondel, the great Dutch poet, and Rembrandt. Vondel wrote a poem for two weddings in the Anslo family: that of Gerbrand Anslo (son of Cornelis) in 1636 and that of Gerbrand's daughter Alida in 1658. Rembrandt painted several portraits of him. The widely known painting, "The Mennonite Preacher C. C. Anslo and a Widow" (or his wife), was purchased by the Prussian government for a large sum and hangs in the National Gallery of Berlin. An etching of the same subject is in the Chicago Art Institute and one of Anslo alone is in the Fogg Museum of Art at Harvard University. The following verse by Vondel is about Anslo.
Ay, Rembrandt maal Cornelis' stemm! Het sichtbre deel is 't minst van hem: 't Onsichtbre kent men slechts door d'ooren; Die Anslo zien wil, moet hem hooren. ("O Rembrandt, draw Cornelis' voice! The visible part is the least of him: the invisible is known only by hearing; he who would see Anslo must hear him.")Below Anslo's picture in an anteroom of the Singel Mennonite Church in Amsterdam are the following lines (in Dutch) by Andr. Spinniker:
Whoever looks at Anslo's picture, his heart is deeply moved by the fiery zeal evident in his eyes; yet could a brush make his voice heard, everyone's heart would be converted to virtuous living.
