Contradiction with Ecclesiastes 11:9
This verse encourages young people to rejoice and follow their heart, which might contrast with the sober-mindedness recommended in Titus 2:6.
Ecclesiastes 11:9: Rejoice, O young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thine heart, and in the sight of thine eyes: but know thou, that for all these [things] God will bring thee into judgment.
Contradiction with 1 Corinthians 13:11
This verse suggests putting away childish things when becoming a man, while Titus 2:6 addresses young men, which might imply a different standard for behavior.
1 Corinthians 13:11: When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. [thought: or, reasoned] [put away: Gr. vanish away]
Contradiction with 1 Timothy 4:12
It emphasizes setting an example in behavior, possibly implying more active guidance rather than just a sober mindset.
1 Timothy 4:12: Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity.
Contradiction with Ecclesiastes 7:16
Advises not to be overly righteous, which might seem contrary to striving for a sober-minded spirit.
Ecclesiastes 7:16: Be not righteous over much; neither make thyself over wise: why shouldest thou destroy thyself? [destroy...: Heb. be desolate?]
