Matthew 28:19 actually says in my traditional King James version of the bible...
Go ye therefore, and TEACH all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Nothing about making disciples of all nations there.
And Matthew 28:20 says...
Teaching them to OBSERVE all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Nothing about forced obedience otherwise known as slavery.
The scriptures bear witness to continued authority in the Church among Elders (presvyteros and episkopos) and deacons (diakonos).
Really? Where specifically. I can recall Paul writing that we should not take religious titles for ourselves, such that would elevate us above others.
So what we're really talking about here is interpretation. My bible version emphasising choice while your bible version emphasises a comfortable job description to carry out.
The actual Apostles were mostly illiterate; saving Paul, so the scriptures were written by all sorts of people (inspired by God of course) but written in their native understanding of the world. For example, Greeks placed great importance on knowledge while Hebrews placed great importance on tradition and ritual.
Which translation actually bears more of the truth? No one honestly knows save the Lord and the Holy Spirit which tesitifies of him.
I'm not saying the bible isn't a credible source of God's intentions for mankind, however, when we follow it literally without reasoning it with the gift of the Holy Spirit we are open to the influences of the generations/cultures who scripted the bible - not the actual truth God was getting at.
The evidence to show that man has gotten it wrong in interpretation before, is the entire Old testiment. His children failed, rebelled against God and then after they were severely punished, they asked God to have mercy on them again to redeem his people. Which he did, but there was a pattern emerging. Peace and prosperity, rebellion against God then punishement from God as he turned away from his rebellious children, and finally redemption when they asked God to take pity on them.
The Old Testiment was written in part during this time. While everyone does their best to represent the Lord and the scriptures (even today) we are bound to have some personal interest in there - yes, even in the churches. Just noting the difference in interpretation from your bible and mine - who's version is right? Neither of us can say that we know for certain either version is without blemish.
