He ordained 12

Judas Iscariot also was ordained to be part of the 12:

Mark 3:14, 19 "14 And he ordained twelve, that they should be with him, and that he might send them forth to preach, 19 And Judas Iscariot, which also betrayed him: and they went into an house."

I wonder if there are any ordained Judas' today?

Jude 4 For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.

Gal. 2:4 And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:

Acts 20:29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
Acts 20:30 Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.

Yes, there might be.
Additionally, although we are not ordained as an elder or minister, we can be "grievous wolves"among God's people.

Yes so many wolves that guild people within the church away while still attending church
