Lelio was the uncle of Fausto Sozzini, for whom the Polish Brethren and early English Unitarians came to be called "Socinians." From Lelio, Fausto derived his theory of salvation and interpretations of specific interpretations of the Bible. Lelio's writings include De Sacramentis dissertatio (On the Sacraments), De resurrectione (On resurrection) and Brevis explicatio in primum Iohannis caput (A short explanation of John I).
