In 1 Timothy 1:3–4, Paul urges Timothy to remain at Ephesus so that he can instruct certain men to cease from teaching strange doctrines. Paul means any teaching that is different from that of Christ and His apostles. These “strange doctrines” result in “mere speculation.” The Greek term is much stronger; it literally means “disputes” or “quarrels.”20
