Whether judiciary power belongs to Christ with respect to all human affairs?

Objections

Objection 1 : It would seem that judiciary power concerning all human affairs does not belong to Christ. For as we read in Lk. 12:13,14, when one of the crowd said to Christ: "Speak to my brother that he divide the inheritance with me; He said to him: Man, who hath appointed Me judge, or divider over you?" Consequently, He does not exercise judgment over all human affairs.
Objection 2 : Further, no one exercises judgment except over his own subjects. But, according to Heb. 2:8, "we see not as yet all things subject to" Christ. Therefore it seems that Christ has not judgment over all human affairs.
Objection 3 : Further, Augustine says (De Civ. Dei xx) that it is part of Divine judgment for the good to be afflicted sometimes in this world, and sometimes to prosper, and in like manner the wicked. But the same was the case also before the Incarnation. Consequently, not all God's judgments regarding human affairs are included in Christ's judiciary power.
