"The Godhead" of 1 John 5:7 probably the MOST attacked biblical verse?!

How is the so-called “Joahinne comma” of 1 John 5:7 to 8, describing the Godhead, probably the most attacked verse in the Bible?
“Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I [am] the first, and I [am] the last; and beside me [there is] no God. ” (Isaiah 44:6)
“I am Alpha and Omega, the beginning and the end, the first and the last.” (Revelation 22:13)
“For in him dwelleth all the fulness of the Godhead bodily.” (Colossians 2:9)
