673. "Since the Ascension Christ's coming in glory has been imminent,[Cf. Rev 22:20.] even though 'it is not for you to know times or seasons which the Father has fixed by his own authority.'[Acts 1:7 ; Cf. Mk 13:32 .]. This eschatological coming could be accomplished at any moment, even if both it and the final trial that will precede it are 'delayed'.[Cf. Mt 24:44 ; 1 Th 5:2 ; 2 Th 2:3-12 .]"
674. "The glorious Messiah's coming is suspended at every moment of history until his recognition by 'all Israel', for 'a hardening has come upon part of Israel' in their 'unbelief' toward Jesus.[Rom I 1:20-26 ; cf. Mt 23:39 .] St. Peter says to the Jews of Jerusalem after Pentecost: 'Repent therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for establishing all that God spoke by the mouth of his holy prophets from of old.'[Acts 3:19-21 .] St. Paul echoes him: 'For if their rejection means the reconciliation of the world, what will their acceptance mean but life from the dead?'[Rom 11:15 .] The 'full inclusion' of the Jews in the Messiah's salvation, in the wake of 'the full number of the Gentiles',[Rom 11:12, 25 ; cf. Lk 21:24 .] will enable the People of God to achieve 'the measure of the stature of the fullness of Christ', in which 'God may be all in all'.[Eph 4:13 ; 1 Cor 15:28 .]"
675. "Before Christ's second coming the Church must pass through a final trial that will shake the faith of many believers.[Cf. Lk 18:8 ; Mt 24:12 .] The persecution that accompanies her pilgrimage on earth[Cf. Lk 21:12 ; Jn 15:19-20 .] will unveil the 'mystery of iniquity' in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. The supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh.[Cf. 2 Th 2:4-12 ; 1 Th 5:2-3 ; 2Jn 7 ; 1Jn 2:1 8, 22 .]"
676. "The Antichrist's deception already begins to take shape in the world every time the claim is made to realize within history that messianic hope which can only be realized beyond history through the eschatological judgement. The Church has rejected even modified forms of this falsification of the kingdom to come under the name of millenarianism,[Cf. DS 3839.] especially the 'intrinsically perverse' political form of a secular messianism.[Pius XI, Divini Redemptoris, condemning the 'false mysticism' of this 'counterfeit of the redemption of the lowly'; cf. GS 20-21.]"
