What is the difference between a church elder who teaches and the calling of Teacher?

I heard it explained before that the universal church teacher is like a doctor and the local church teacher is like a nurse. The point being, one is a master at it and this master teacher is called, anointed and appointed by God to be a teacher to the whole Body of Christ - the church universal. Such a teacher must be a master of the Bible and knows God well because he ranks third in universal Church authority; apostle prophet, teacher. (1 Co 12:28). Jesus often sent prophets and teachers to the Church universal. (Mt 23:34; Acts 13:1)

The other is less than a master teacher is in essence an elder in the church thus is part of the team of elders who are responsible to God for shepherding that church.(Acts 20:17,28) The elder must be apt or able to teach (1Tim 3:2) and ranks first in local church authority along with the other elders. (1 Tim 5:17; Heb 13:17)

Teachers have God given spiritual authority over others. The elder/teacher has this authority over the local flock and the master teacher has it over the entire Body of Christ. (Mk 1:22) This is why Paul would not allow women to be teachers because a teacher has authority over men. (1Tim 2:12) I won't get into the whole male female ministry issue but am simply establishing the truth that teachers have authority over others whether they are male or female teachers.

Not many should be master teachers because they will be held to a stricter accountability. (Jas 3:1) but many can be elder/teachers (Heb 5:11,12; Col 3:16)

No one can be appointed by man to be a master teacher, only God can call and appoint and anoint a master teacher. (2 Tim 1:11; 1 Cor 12:28)
On the other hand, one can desire to be an elder/teacher (1 Tim 3:1) and can be appointed as an elder/teacher by man and then God anoints them "which the Holy Spirit HAS MADE YOU overseers" Acts 20:26. Some believe that man makes elders but that verse points out that the Holy Spirit does it after man appoints them (see also Titus 1:5).

Teachings are treasures, some old and some new (Mt 13:52)
The master teacher has teachings which are treasures for all.
The elder teacher has teachings which are treasures for that particular church and satisfies the regular teaching needs of the local church.

Any teacher should be able to teach what is old treasure - the established sound doctrines (Titus 2:1) and should also be able to discover new treasures in scripture themselves which do not contradict sound doctrine and teach them too. (Mt 13:52)

In my opinion, one that cannot discover new treasures themselves in scripture lacks the anointing from God to teach and should not be a teacher. This is something that I view as a major distinction between an Old Covenant teacher and a New Covenant teacher. The OC teacher mastered the law and taught only the established law of Moses. The NC teacher has the Holy Spirit which always is teaching new things to us, which are new treasures as he opens the scriptures more and more to us. (Jn 14:26)

Eight basic things teachers are to do
1. Teach old treasures which is sound doctrine (Mt 13:52; Titus 2:1)
2. Teach new treasures which are not in conflict with sound doctrine. (Mt 13:52)
3. Obey their own teaching (Rom 2:21-24)
4. Teach others to obey the teaching (Mt 28:20; Jn 15:20)
5. Teach the whole Bible and the whole counsel of God (Acts 18:11; Acts 20:27)
6. Stay within God's appointed boundaries - local stay local, universal stay universal. (Jn 3:27; Tit 1:5; Acts 20:28; Acts 13:1)
7. Address the needs of the people (Mt 24:45)
8. Make disciples (Mt 28:18-20)

Some areas where a teacher may fail:
1. Neglecting to teach sound doctrine is a mistake.
This is where I feel many seminary professors err. Teaching church history or Bible history is not teaching sound doctrine nor is it teaching false doctrine, it is teaching no doctrine at all and instead it is teaching history thus it is neglecting to teach sound doctrine and such is not what the Bible calls a teacher. Teaching Hebrew or Greek is not teaching sound doctrine it is teaching language, nothing wrong with that but it's not a Bible teacher. Teaching Biblical archeology, Biblical criticism etc. is not teaching sound doctrine. Such teachers are academic or educational teachers equal to a math or science teacher and there is nothing wrong with that but they are not Spiritual teachers equal to a Bible teacher and therefore they do not need the Holy Spirit, nor a call from God, nor an anointing nor an appointing by God to do what they do. Teaching all sorts of things instead of the Bible does not equate to a Teacher as we see in 1Co 12:28 & Eph 4:11 nor an elder/teacher as we see in many passages describing elders.

2. Teaching new things which contradict sound doctrine and/or scripture is a mistake.
Such teachings are false teachings and false doctrines and some teachings are even called doctrines of demons and secrets of Satan according to the Bible. (1 Tim 4:1; Rev 2:24) Teachers that teach false things are mistaken and depending on the level of the mistake one may even be qualified as a false teacher according to the Bible. Mistaken teachers can be corrected but false teachers are doomed according to (2 Pet 2)
Therefore not many should be teachers (Jas 3:1) And all teachers should watch their doctrine carefully (1Tim 4:16; Col 2:18,19)

3. Disobeying their own teaching is a mistake.
Such are called hypocrites and Jesus spoke the most sever woes of all to the teachers who did this. Paul said to Timothy watch your doctrine and your life too (1Tim 4:16) Or you will be disqualified (1Co 9:27)

4. Failing to help others obey but simply teaching as if it didn't matter what the people do with the teaching is a mistake.
Jesus rebuked the Pharisees for this sin. (Lk 11:46) Also teaching deep and difficult things without further explanation to ensure understanding is a mistake too. Jesus taught many things that they could not understand but he continued to explain until they did understand - answering all their questions. There is a difference between spiritual milk and meat. (1Co 3:2; Heb 5:12,13; 1Pet 2:2; 1Co 2:6)

5. Teaching only part of the Bible or part of the counsel of God is a mistake.
This area too I feel many seminary professors fail in. Because they teach only part and specialize in Old Testament or this or that. I also see this failure in many elders who specialize in "End times" or the "Prophetic" or "Gifts" etc. I see nothing wrong with specializing in areas as long as such special attention is added to the teaching of the whole Bible and the whole counsel of God rather than replacing it. (Acts 20:27; Rom 15:4)

6. An elder teacher of a local church who tries to be a master teacher of the entire Body of Christ is a mistake.
They may travel around teaching shallow milk teachings or write books of shallow milk teachings and thus are going outside of the boundaries God has set for them.
Likewise a master teacher who does not travel and teach the deep meaty things to the whole Body of Christ but instead stays at a local church and/or does not write books or impact the whole Body is also out of bounds.
Today I think most western Christian writers are not really teachers to the whole Body of Christ they have an elder anointing and not a teacher anointing - but they make allot of money selling books :) and end up dumbing down or watering down the whole body of Christ in the process.There is a difference between spiritual milk and meat. (1Co 2:6; 1Co 3:2; Heb 5:12-14; 1Pet 2:2)

7. Failing to teach things that the people need right now is a common error.
It's okay to teach all sorts of series and things as long as they are added to what the people need at the moment and do not replace it.

8. Making intellectual Bible students but failing to make disciples of Jesus is a mistake.
Jesus never commanded us to become only Bible students. Being a student of the Word is good and is part of being a disciple of Jesus and not the other way around. Knowing God takes both deep Bible knowledge and deep relationship with Jesus.
