Need someone up on Luther to answer this. In his commentary on Revelation, James Durham writes, "Luther’s work ascended by these steps: 1. In his Theses, given out, anno 1517, against indulgences, and thereafter in their defense against Sylvester, Eccius, Pererius and others, he shows these things profit not to life, but repentance and faith resting only on Christ’s merits and the mercy of God alone, seeing no saint’s merits are perfect." Has Durham mistakenly referred to Sylvester Pererius twice; or maybe a printer's error? Or is there some other Sylvester Luther disputed famously over the Theses? One would think if the three main were named, the first Sylvester maybe should have been Thomas Cajetan? Ideas?
