Doctrinal Roadblocks to UOJ from the Formula of Concord

So how can anyone say the whole world is declared righteous? (UOJ dogma)
3] 2. Likewise we believe, teach, and confess that the unregenerate will of man is not only turned away from God, but also has become an enemy of God, so that it only has an inclination and desire for that which is evil and contrary to God, as it is written Gen. 8:21: The imagination of man's heart is evil from his youth. Also Rom. 8:7: The carnal mind is enmity against God; for it is not subject to the Law of God, neither, indeed, can be. Yea, as little as a dead body can quicken itself to bodily, earthly life, so little can man, who by sin is spiritually dead, raise himself to spiritual life, as it is written Eph. 2:5: Even when we were dead in sins, He hath quickened us together with Christ; 2 Cor. 3:5: Not that we are sufficient of ourselves to think anything good as of ourselves, but that we are sufficient is of God.

How does one become righteous?
4] 3. God the Holy Ghost, however, does not effect conversion without means, but uses for this purpose the preaching and hearing of God's Word, as it is written Rom. 1:16: The Gospel is the power of God 5] unto salvation to every one that believeth. Also Rom. 10:17: Faith cometh by hearing of the Word of God. And it is God's will that His Word should be heard, and that man's ears should not be closed. Ps. 95:8. With this Word the Holy Ghost is present, and opens hearts, so that they, as Lydia in Acts 16:14, are attentive to it, and are thus converted alone through the grace and power of the Holy Ghost, whose 6] work alone the conversion of man is. For without His grace, and if He do not grant the increase, our willing and running, our planting, sowing, and watering, all are nothing, as Christ says John 15:5: Without Me ye can do nothing. With these brief words He denies to the free will its powers, and ascribes everything to God's grace, in order that no one may boast before God. 1 Cor. 1:29; 2 Cor. 12:5; Jer. 9:23.

UOJ is pure Enthusiasm
13] 6. Also, we reject and condemn the error of the Enthusiasts, who imagine that God without means, without the hearing of God's Word, also without the use of the holy Sacraments, draws men to Himself, and enlightens, justifies, and saves them. (Enthusiasts we call those who expect the heavenly illumination of the Spirit [celestial revelations] without the preaching of God's Word.)

Does this sound like UOJ? Few pastors read or study this, so how can they confess it?
18] 9. Also what Dr. Luther has written, namely, that man's will in his conversion is pure passive, that is, that it does nothing whatever, is to be understood respectu divinae gratiae in accendendis novis motibus, that is, when God's Spirit, through the Word heard or the use of the holy Sacraments, lays hold upon man's will, and works [in man] the new birth and conversion. For when [after] the Holy Ghost has wrought and accomplished this, and man's will has been changed and renewed by His divine power and working alone, then the new will of man is an instrument and organ of God the Holy Ghost, so that he not only accepts grace, but also cooperates with the Holy Ghost in the works which follow.

19] Therefore, before the conversion of man there are only two efficient causes, namely, the Holy Ghost and the Word of God, as the instrument of the Holy Ghost, by which He works conversion. This Word man is [indeed] to hear; however, it is not by his own powers, but only through the grace and working of the Holy Ghost that he can yield faith to it and accept it.

The Word of God is the instrument of conversion.
6] 5. This [predestination of God] is not to be investigated in the secret counsel of God, but to be sought in the Word of God, where it is also revealed.

7] 6. But the Word of God leads us to Christ, who is the Book of Life, in whom all are written and elected that are to be saved in eternity, as it is written Eph. 1:4: He hath chosen us in Him [Christ] before the foundation of the world.

8] 7. This Christ calls to Himself all sinners and promises them rest, and He is in earnest [seriously wills] that all men should come to Him and suffer themselves to be helped, to whom He offers Himself in His Word, and wishes them to hear it and not to stop their ears or [neglect and] despise the Word. Moreover, He promises the power and working of the Holy Ghost, and divine assistance for perseverance and eternal salvation [that we may remain steadfast in the faith and attain eternal salvation].
