The purification of Church
Only after the division of Christianism, is that theologian pastors multiplied, and all kind (because is a good profession, pays well, is venerated). But the Lord Jesus will resume as the supreme Shepherd and his sheep, and purify the church and ask account to the unfaithful pastors, as said in Ezekiel 34:
4- The diseased have ye not strengthened, neither have ye healed that which was sick, neither have ye bound up [that which was] broken, neither have ye brought again that which was driven away, neither have ye sought that which was lost; but with force and with cruelty have ye ruled them..
10- Thus saith the Lord GOD; Behold, I [am] against the shepherds; and I will require my flock at their hand, and cause them to cease from feeding the flock; neither shall the shepherds feed themselves any more; for I will deliver my flock from their mouth, that they may not be meat for them.
And confirms in Jeremiah 25.34 to 38 -
You only have to read what God is going to do with those that only take advantage of

the sheep, and don’t feed them like a shepherd should, just as is hRevpening now. God spoke also to Ezekiel still in 34 that he’ll judge the fat sheep that with the example of the shepherds are there, taking advantage of the Best of the worlds, many times at expenses of the poorer brothers.
18- [Seemeth it] a small thing unto you to have eaten up the good pasture, but ye must tread down with your feet the residue of your pastures? and to have drunk of the deep waters, but ye must foul the residue with your feet?
19- And [as for] my flock, they eat that which ye have trodden with your feet; and they drink that which ye have fouled with your feet.
20- Therefore thus saith the Lord GOD unto them; Behold, I, [even] I, will judge between the fat cattle and between the lean cattle.
23- And I will set up one shepherd over them, and he shall feed them, [even] my servant David; (Jesus) he shall feed them, and he shall be their shepherd.
(Jesus, the root of David, the Lion of Judah).
