Returning to his home priory at Constance in about 1327, Suso was appointed to the office of "lector" (lecturer). His teaching, however, aroused criticism – most likely because of his connection with Eckhart in the wake of the latter's trial and condemnation in 1326–29. Suso's "Little Book of Truth", a short defence of Eckhart's teaching, probably dates from this time, perhaps 1329. In 1330 this treatise, and another, were denounced as heretical by enemies in the Order. Suso traveled to the Dominican General Chapter held at Maastricht in 1330 to defend himself. The consequence is not entirely known – at some point between 1329 and 1334 he was removed from his lectorship in Constance, though he was not personally condemned.
