LOL! “alone” is not needed if you are talking about, German, Greek, English, French, Swahili, or Martian.
and since the NT was written by, to and for the Church, it has every right to complain about individuals “editorializing” their own opinions of what the verses should say into the text.
we certainly object to when the Jehovah’s Witnesses or the Mormons do it, don’t we?
The Catholic Church under the leadership of the Pope had nothing to do with the writing of scripture.
And the Catholic Church violently opposed allowing commoners to read scripture. It wasn’t a ‘bad translation’ they opposed, but common people reading God’s Word.
And if you will read my link, you will find that translations authorized by the Catholic Church DID add ‘alone’:
The Roman Catholic writer Joseph A. Fitzmyer points out that Luther was not the only one to translate Romans 3:28 [Open in Logos Bible Software (if available)] with the word “alone.”
At 3:28 Luther introduced the adv. “only” into his translation of Romans (1522), “alleyn durch den Glauben” (WAusg 7.38); cf. Aus der Bibel 1546, “alleine durch den Glauben” (WAusg, DB 7.39); also 7.3-27 (Pref. to the Epistle). See further his Sendbrief vom Dolmetschen, of 8 Sept. 1530 (WAusg 30.2 [1909], 627-49; “On Translating: An Open Letter” [LuthW 35.175-202]). Although “alleyn/alleine” finds no corresponding adverb in the Greek text, two of the points that Luther made in his defense of the added adverb were that it was demanded by the context and that sola was used in the theological tradition before him.
Robert Bellarmine listed eight earlier authors who used sola (Disputatio de controversiis: De justificatione 1.25 [Naples: G. Giuliano, 1856], 4.501-3):
Origen, Commentarius in Ep. ad Romanos, cap. 3 (PG 14.952).
Hilary, Commentarius in Matthaeum 8:6 (PL 9.961).
Basil, Hom. de humilitate 20.3 (PG 31.529C).
Ambrosiaster, In Ep. ad Romanos 3.24 (CSEL 81.1.119): “sola fide justificati sunt dono Dei,” through faith alone they have been justified by a gift of God; 4.5 (CSEL 81.1.130).
John Chrysostom, Hom. in Ep. ad Titum 3.3 (PG 62.679 [not in Greek text]).
Cyril of Alexandria, In Joannis Evangelium 10.15.7 (PG 74.368 [but alludes to Jas 2:19 [Open in Logos Bible Software (if available)] ]).
Bernard, In Canticum serm. 22.8 (PL 183.881): “solam justificatur per fidem,” is justified by faith alone.
Theophylact, Expositio in ep. ad Galatas 3.12-13 (PG 124.988).
To these eight Lyonnet added two others (Quaestiones, 114-18):
Theodoret, Affectionum curatio 7 (PG 93.100; ed. J. Raeder [Teubner], 189.20-24).
Thomas Aquinas, Expositio in Ep. I ad Timotheum cap. 1, lect. 3 (Parma ed., 13.588): “Non est ergo in eis [moralibus et caeremonialibus legis] spes iustificationis, sed in sola fide, Rom. 3:28 [Open in Logos Bible Software (if available)] : Arbitramur justificari hominem per fidem, sine operibus legis” (Therefore the hope of justification is not found in them [the moral and ceremonial requirements of the law], but in faith alone, Rom 3:28 [Open in Logos Bible Software (if available)] : We consider a human being to be justified by faith, without the works of the law). Cf. In ep. ad Romanos 4.1 (Parma ed., 13.42a): “reputabitur fides eius, scilicet sola sine operibus exterioribus, ad iustitiam”; In ep. ad Galatas 2.4 (Parma ed., 13.397b): “solum ex fide Christi” [Opera 20.437, b41]).

The Catholic Church’s objection to Luther’s translation was that commoners COULD and DID read it.
