How do you see the similarity between the ideas of the 13th century heretics and the preaching of Jan Hus?

In the views of the heretics of the XIII century. and the sermons of Jan Hus, the following similar ideas can be distinguished: both heretics and J. Hus opposed the papacy and the official church, which they accused of greed, debauchery, enrichment at the expense of the common people. Denying the special position of the pope, denouncing the morals of the clergy, J. Hus also rejected the practice of the sacrament, believing that the ministers of the church and the laity should receive communion in the same way, since this had a social significance: everyone is equal in the face of the Lord, the clergy should not have privileges.
