What are the objections to Newton's critique of 1 John 5:7 and 1 Timothy 3:16? In &quot;An Historical Account of Two Notable Corruptions of Scripture&quot;, Isaac Newton argued that 1 John 5:7 was a corruption of the early church and did not appear in the original Greek scriptures. He makes a similar claim regarding 1 Timothy 3:16. 1 John 5:7 is the strongest biblical reference to the trinity. Is there an objection to Newton's historical analysis of these verses?

1 John 5:7 -- For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
1 Timothy 3:16 -- And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.
1 John 5:7, 8

It is NOT included in Wescott &amp; Hort, NA28, UBS5, SBL, Majority Text, Byzantine Text, F35, Jerome's Vulgate (~400 AD), THGNT, NIVGNT.

It is included on the Orthodox text (by edict), TR and Clementine Vulgate.  It is clearly a late addition from the vulgate.

1 Tim 3:16

The difference in this verse is "theos" (= God in TR and majority Byzantine text) vs "hos" (= he or who in NA28, UBS5 etc).  In any case the sense of the verse is scarcely changed.

The problem with Newton's critique is his dependence on a straw-man argument.  Because two texts supporting the Trinitarian view are dubious, then is Trinitarianism dubious?  Hardly.  There are numerous other arguments in favour of Trinitarianism in the NT.
