2 Thessalonians 2 Revised Standard Version Catholic Edition (RSVCE)
The Man of Lawlessness
2 Now concerning the coming of our Lord Jesus Christ and our assembling to meet him, we beg you, brethren, 2 not to be quickly shaken in mind or excited, either by spirit or by word, or by letter purporting to be from us, to the effect that the day of the Lord has come.[a] 3 Let no one deceive you in any way; for that day will not come, unless the rebellion comes first, and the man of lawlessness[b][c] is revealed, the son of perdition, 4 who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God. 5 Do you not remember that when I was still with you I told you this? 6 And you know what is restraining him now so that he may be revealed in his time. 7 For the mystery of lawlessness is already at work; only he who now restrains it will do so until he is out of the way.[d] 8 And then the lawless one will be revealed, and the Lord Jesus will slay him with the breath of his mouth and destroy him by his appearing and his coming. 9 The coming of the lawless one by the activity of Satan will be with all power and with pretended signs and wonders, 10 and with all wicked deception for those who are to perish, because they refused to love the truth and so be saved. 11 Therefore God sends upon them a strong delusion, to make them believe what is false, 12 so that all may be condemned who did not believe the truth but had pleasure in unrighteousness.
Chosen for Salvation
13 But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God chose you from the beginning[e] to be saved, through sanctification by the Spirit[f] and belief in the truth. 14 To this he called you through our gospel, so that you may obtain the glory of our Lord Jesus Christ. 15 So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.
16 Now may our Lord Jesus Christ himself, and God our Father, who loved us and gave us eternal comfort and good hope through grace, 17 comfort your hearts and establish them in every good work and word.
2 Thessalonians 2 New International Version (NIV)
The Man of Lawlessness
2 Concerning the coming of our Lord Jesus Christ and our being gathered to him, we ask you, brothers and sisters, 2 not to become easily unsettled or alarmed by the teaching allegedly from us—whether by a prophecy or by word of mouth or by letter—asserting that the day of the Lord has already come. 3 Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness[a] is revealed, the man doomed to destruction. 4 He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God.
5 Don’t you remember that when I was with you I used to tell you these things? 6 And now you know what is holding him back, so that he may be revealed at the proper time. 7 For the secret power of lawlessness is already at work; but the one who now holds it back will continue to do so till he is taken out of the way. 8 And then the lawless one will be revealed, whom the Lord Jesus will overthrow with the breath of his mouth and destroy by the splendor of his coming. 9 The coming of the lawless one will be in accordance with how Satan works. He will use all sorts of displays of power through signs and wonders that serve the lie, 10 and all the ways that wickedness deceives those who are perishing. They perish because they refused to love the truth and so be saved. 11 For this reason God sends them a powerful delusion so that they will believe the lie 12 and so that all will be condemned who have not believed the truth but have delighted in wickedness.
13 But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruits[b] to be saved through the sanctifying work of the Spirit and through belief in the truth. 14 He called you to this through our gospel, that you might share in the glory of our Lord Jesus Christ.
15 So then, brothers and sisters, stand firm and hold fast to the teachings[c] we passed on to you, whether by word of mouth or by letter.
16 May our Lord Jesus Christ himself and God our Father, who loved us and by his grace gave us eternal encouragement and good hope, 17 encourage your hearts and strengthen you in every good deed and word.
