*3:2 Since everyone believes something, has a worldview, the reference is presumably to faith in God.

†3:3 ‘The’ malignant one is Satan.

‡3:4 Observe that Paul considers that he is in a position to command.

§3:5 As Paul makes clear in the opening paragraph, they are already manifesting love and perseverance, so I take the point of the prayer to be progress into God's kind of love and Christ's kind of perseverance. They have made a good start, they are on the right road; Paul asks God to help them on toward the goal.

*3:6 There were several of them.

†3:8 The distinction implied here indicates that the irresponsible behavior covered a wider area than just idleness or freeloading.

‡3:10 “Does not want to work”—the reference is not to those who want to work but cannot find a job; it is to the lazy.

§3:15 The discipline is to be corrective, not punitive. Note that Paul clearly claims authority; he expects to be obeyed.

*3:16 “The peace”: there is no lack of counterfeit ‘peace’, but the reference here is presumably to ‘the peace of God, that surpasses all understanding’ (Philippians 4:7)—and only “the Lord of peace” can give it.

†3:16 Since they were being actively persecuted, this was a very appropriate blessing.

‡3:17 I take the clear implication to be that Paul dictated his letters to an amanuensis, or secretary, but ‘signed’ the letter by writing the last line himself.
