You originally said, "The word heretick comes from 2 Greek words and means opinionated one." It does not come from two Greek words dcontroversal it comes from one (Strong #138 αἱρέω). And it does not mean opinionated. Please Look at the LSJ below. Plato used the root of the word (Strong's#138) in the sense of "able to choose". It is a choice not opinionated.
Due to the context in Titus 3:10 this choice can have negative cogitation causing division; hence the second entry factious; schismatic, a division maker; however not opinionated.
From the LSJ
αἱρετ-ικός , ή , όν , ( αἱρέω )
able to choose , Pl. Def. 412a ;
due to choice , οἰκείωσις Hierocl. p.41.5A. , Anon. in Tht. 7.40.
2. factious, Ep.Tit. 3.10.
3. Astrol., belonging to the 'condition' , Paul.Al. Q. 2.
4. Adv. -κῶς from choice , D.L. 7.126 , Hierocl. p.41.7 A.
Apparently this factious nature of the word as used in Titus is all that Bauer deemed worthy of noting.
From the BDAG
αἱρετικός, ή, όν (in Ps.-Pla., Definit. 412a; Aelian, NA 6, 59; Hierocles Stoic. [I/II A.D.] Eth. 9, 5; here 7 and Diog. L. 7, 126 also the adv.; subst. pl. οἱ αἱ. Iren. 5, 13, 2 [Harv. II 356, 8] al.) pert.
to causing divisions, factious, division-making. ἄνθρωπος αἱ.
division-maker Tit 3:10 (s. αἵρεσις 1b, c).—TW.
Mounce concurs in his work.
G141
αἱρετικός hairetikos 1x
one who creates or fosters factions, Tit_3:10
As does Thayer in his unabridged work
G141
αἱρετικός, (ή, (see
αἱρέω);
1.
fitted or able to take or choose a thing; rare in secular authors.
2.
schismatic, factious, a follower of false doctrine: Tit_3:10.
Incidentally HELPS Word-studies is not lexicon used in any seminary or College that I know of. And it does not say the word means opinionated, it says it means A factious person. nor does it cite that the words comes from two Greek words.
Cognate: 141 hairetikós (an adjective, derived from
138 /hairéomai, "to choose, have a distinctive opinion")
– a factious person, specializing in half-truths and misimpressions "to win others over" to their
personal opinion(
misguided zeal) – while creating
harmful divisions (used only in Tit 3:10).
See 139 (
hairesis).
