Most Christian traditions[136][137][138] say Paul clearly portrays homosexuality as sinful in two specific locations: Romans 1:26–27, and 1 Corinthians 6:9–10. Another passage addresses the topic more obliquely: 1 Timothy 1:8–11. Since the nineteenth century, however, most scholars have concluded that 1 Timothy, along with 2 Timothy and Titus, are not original to Paul, but rather an unknown Christian writing in Paul's name some time in the late-first-to-mid-2nd century.[139][140]
