Advocates for Christian polygamy point to Titus 1:6 and 1 Timothy 3:2, 12, arguing that the phrase "one wife" uses the Greek word mia, which they claim can also be translated as "first" (e.g., as in the "first day of the week" in Matthew 28:1). They argue this means a church leader must only have his first wife, allowing for others.

This interpretation reveals a deep misunderstanding of the Greek text. As scholars have repeatedly demonstrated, attempting to translate mia as "first" in this context violates basic Greek grammar and syntax. The requirement is clearly monogamy, not a sequential ranking of multiple wives.
