Through contact with teachers and students from various parts of Europe while he was studying at the University of Padua, Algieri was introduced to so - called heretics and to Protestant Reformation doctrines.
Oma õpingute ajal Padova ülikoolis puutus Algieri kokku Euroopa eri paikadest pärit õppejõudude ja üliõpilastega ning nende kaudu sai ta tuttavaks nn. ketserite ja protestantidest reformaatorite õpetustega.
