John Calvin on Philippians 1:26

26 That your glorying. The expression which he employs, ἐν ἐμόι, I have rendered de me (as to me,) because the preposition is made use of twice, but in different senses. No one assuredly will deny that I have faithfully brought out Paul’s mind. The rendering given by some — per Christum, (through Christ,) I do not approve of. For in Christ is employed in place of Secundum Christum, (According to Christ,) or Christiane, (Christianly,) to intimate that it was a holy kind of glorying. For otherwise we are commanded to glory in God alone. (1 Corinthians 1:31.) Hence malevolent persons might meet Paul with the objection, How is it allowable for the Philippians to glory as to thee? He anticipates this calumny by saying that they will do this according to Christ — glorying in a servant of Christ, with a view to the glory of his Lord, and that with an eye to the doctrine rather than to the individual, and in opposition to the false apostles, just as David, by comparing himself with hypocrites, boasts of his righteousness. (Psalm 7:8.)

Philippians 1:27-30

27. Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;

27. Tantum digne Evangelio Christi conversamini: ut sive veniens videam vos, sive absens, audiam de vobis, quod stetis in uno spiritu, una anima, concertantes fide Evangelii.

28. And in nothing terrified by your adversaries: which is to them an evident token of perdition, but to you of salvation, and that of God.

28. Nec ulla in re terreamini ab adversariis, quae illis est demonstratio exitii: vobis autem salutis, idque a Deo.

29. For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;

29. Quia vobis donatum est pro Christo, non tantum ut in illum credatis, sed etiam ut pro ipso patiamini:

30. Having the same conflict which ye saw in me, and now hear to be in me.

30. Idem habentes certamen, quale vidistis in me, et nunc auditis de me.
