Lelio Sozzini (uncle of Socinus) wrote Brevis explicatio in primum Johannis caput, a commentary on the meaning of the Logos in John 1:1–15, and it was published in 1562. Sozzini held that the 'beginning' of John 1:1 was the same as 1 John 1:1, and both were about a new creation, not a Genesis creation.
His nephew (Socinus) then also wrote a longer Brevis explicatio which expanded on the original.
Have either of these works been translated into English?
