Ordained Preachers

Catholics have taught you must be sent by the Catholic Church to preach. Many other churches teach you have to be ordained. by an authorized group.

This isn't actually biblical.

According to Acts anyone can go around preaching.

Act 8:4  Therefore they that were scattered abroad went every where preaching the word.

If we get scattered abroad we can preach Christ all we want. We do not have to be ordained.

Also, laying hands did not have to be by Bishops and Elders as Catholics teach. Laying hands do not ordain preachers, but is an act of formal prayer to send them off somewhere.

Act 13:3  And when they had fasted and prayed, and laid their hands on them, they sent them away.

At the time there were no Bishops (Elders) ordained in Antioch, it seems they were given Elders in Acts 14 when the Apostles came back to the city.

Act 14:21  And when they had preached the gospel to that city, and had taught many, they returned again to Lystra, and to Iconium, and Antioch,

Act 14:22  Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God.

Act 14:23  And when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed.

Ordination was for elders and not to authorize all preaching. As in Antioch laying hands wasn't for ordination of Paul and Barnabas, but to send them forth with prayer.

The idea of being sent was a prophecy about the apostles. Similar to Isaiah 52.

It didn't imply all have to be sent to preach, but those beginning the restoration had to be sent.

Robertson's word pictures

How beautiful (Hōs hōraioi). A quotation from Isa_52:7 more like the Hebrew than the lxx, picturing the messengers of the restoration from the Jewish captivity. Paul assumes that the missionaries (apostoloi) have been sent as implied in Rom_10:14.

It does not require a formal ordination for people taught by those officially sent. The church fathers saw Isaiah 52 and the corresponding usage in Romans 10 as the Apostles being sent, not that all must be sent.

Irenaeus

86. If then the prophets prophesied that the Son of God was to appear upon the earth, and prophesied also where on the earth and how and in what manner He should make known His appearance, and all these prophecies the Lord took upon Himself; our faith in Him was well-founded, and the tradition of the preaching (is) true: that is to say, the testimony of the apostles, who being sent forth by the Lord preached in all the world the Son of God, who came to suffer, and endured to the destruction of death and the quickening of the flesh: that by the putting away of the enmity towards God, which is unrighteousness, we should obtain peace with Him, doing that which is pleasing to Him. And this was declared by the prophets in the words: How beautiful are the feet of them that bring tidings of peace, and of them that bring tidings of good things.235And that these were to go forth from Judaea and from Jerusalem, to declare to us the word of God, which is the law for us, Isaiah says thus: For from Sion shall come |141 forth the law, and the word of the Lord from Jerusalem.236 And that in all the earth they were to preach, David says: Into all the earth went forth their speech, and their words to the ends of the world.237 Irenaeus, The Proof of the Apostolic Preaching (1920) pp. 69-151.

He used those being sent as the Apostles to us. That was his understanding.
