I wouldn't want to overstate the matter, but there are certain verses which, in the Critical Text, seem to be just plain wrong. For instance:-
Eph 3:14-15, NKJV. 'For this reason I bow my knees to the Father of our Lord Jesus Christ, from whom the whole family in heaven and earth is named.
Eph 3:14-15, ESV. 'For this reason I bow my knees to the Father, from whom every family in heaven and earth is named.'
What is the name given to every follower of Christ, past and present? Why, Christian! The whole family in heaven and earth is named after Christ.
Luke 4:44-5:1, NKJV. 'And He was preaching in the synagogues of Galilee. So it was, as the multitudes pressed about Him to hear the word of God, that He stood by the lake of Gennesaret.'
Luke 4:44-5:1, ESV. 'And he was preaching in the synagogues of Judea. On one occasion, while the crowd was pressing in on him to hear the word of God, he was standing by the lake of Gennesaret.'
Lake Gennesaret is in Galilee, not Judea. Compare these verses with Mark 1:39 to see how the ESV contradicts itself. Bear in mind that the chapter divisions are non-inspired.
Matt 1:8, NKJV. 'Asa begot Jehoshaphet'
Matt 1:8, ESV. 'Asaph the father of Jehoshaphet.'
Check out 1Kings 22:41 etc to see which is correct.
There are two or three other examples that I could give. The NIV and NASB agree with the ESV. It does seem to me that the CT makes the Bible contradict itself in some places.
