The two words commonly used for “one” in the greek NT are heis, and its irregular feminine version mia. It has been put forward by some that when the bible says an Elder or a Deacon must be the husband of one wife, what it really means is “at least one” on the strength that in a minority of cases, mia is translated as “first”, and that if the intent was for it to be only one, the word heis would have been used.
On the outset, it should be pointed out that heis has, in a minority of cases, been translated as ‘some’, so I suppose I would be writing something similar to this no matter which word Paul had used.
To address the mia = first business, um… first: The word is translated first 8 times. 7 times it is in the phrase “first day of the week”. There is awkwardness there because the Jews did not name their days like the Greeks did, (none of this moon-day or Thor’s day stuff) nor did they use a Greek contrivances to speak of “a week”. There was THE Sabbath, and there was one of Sabbath, (which we would call Monday). When speaking of days of the week they used both mia sabbaton and protos sabbaton to mean ‘Monday’. Protos sabbaton would mean “first (day) of the Sabbath”, while mia sabbaton would be best translated “(day) one of the Sabbath”. Both would have been used in that day and location, and both would have given the same information (… so you mean moon-day, right?); but to translate them both the exact same according to our more common English phraseology “first day of the week” leads to confusion. And to build a doctrine based on it is, I believe, dangerous.
Titus 3:10 Therefore gets to stand alone as (in some translations) as rejecting a divisive person after “a first and second admonition” . My belief is that warning them “once and again” is a closer approximation, given the rest of scripture’s use of the word.
Now onto the math!
Matt 5:18 mia = heis
Matt 17:4 mia + mia +mia = Three (also in Mark 9 and Luke 8)
Matt 24:40 Two – heis = mia
Matt 24:41 Two – mia = mia
2 COR 11:24 40 – mia = Traditionally 39. Mentioning for category completion.
Gal 4:24-25 mia covenant + Jerusalem’s covenant = Two covenants
Rev 9:12 mia woes + two woes = three woes (not all in this verse, but read it, yo)
Somebody has the algebra skills to figure out the mathematical values for mia and heis. I won’t spoil the surprise.
Now, if you’re still looking to make mia mean “one or more”, I would also like you to read Ephesians 4:4-5 and tell me exactly how many hopes of our calling and baptisms are in view here.
