When Abbot Burchard[Note 1] openly taught that the souls of the just had gone to heaven before the Resurrection of Christ, Berchtold himself wrote Apologia contra errorem Burchardi Abbatis S. Joannis in Thurthal seu Vallis Taurinae.
Berchtold procured for his monastery many financial privileges, among which was the right to levy tithes upon the churches of Stanz and Buochs, which were under his jurisdiction.
Later chronicles state that, through his blessing, the lake near Stanzstad was stocked with fish, and that shortly before his death he three times changed water into wine.
His miracle of turning water into wine is also mentioned in an epigram beneath a representation of him which was kept in the choir of Engelberg up to the seventeenth century.
At Engelberg his feast is celebrated on the anniversary of his death, and within the Roman Catholic Church he is now also known as "Blessed Berchtold".
