1 Timothy warns against myths, endless genealogies, vain discussion, and would-be teachers of the law; Titus warns against Jewish fables, human commands, empty talkers, and later genealogical/law controversies.

Jesus teaches that moral defilement comes from within rather than merely from external contact; Titus similarly says the defiled and unbelieving are corrupted in mind and conscience even while pursuing purity claims.

Acts 17 and Titus 1 both incorporate lines from nonbiblical Greek poetic tradition as rhetorical witnesses within a biblical argument. Acts and Titus both incorporate recognizable nonbiblical Greek poetic material within apostolic proclamation or exhortation.

1 Corinthians 15:33 and Titus 1:12 both use recognizable nonbiblical Greek sayings/poetry within apostolic exhortation. Paul’s use of an external maxim in 1 Corinthians supplies a clear canonical parallel to the use of a Cretan poetic saying in Titus.

1 Timothy warns of false teaching involving restrictive commands about food and affirms God’s creation as good; Titus warns against Jewish fables and human commands while saying “unto the pure all things are pure.”
