I found a readable translation here:
Didache. The Teaching of the Twelve Apostles (translation Roberts-Donaldson).
It is very interesting reading.
I want to comment on a passage:
"For in the last days false prophets and corrupters shall be multiplied, and the sheep shall be turned into wolves, and love shall be turned into hate; for when lawlessness increases, they shall hate and persecute and betray one another, and then shall appear the world-deceiver as Son of God, and shall do signs and wonders, and the earth shall be delivered into his hands, and he shall do iniquitous things which have never yet come to pass since the beginning."
This reminds me of a thought I had after reading
Orthodoxy and Heterodoxy which describes the history of Christianity. It describes the race to the bottom in the competition between the Protestant sects for members which ultimately led to most of Protestantism becoming a free pass to heaven by just "accepting Jesus". Protestantism started out quite strict and moral but then decayed. And I thought, if I were Satan 200 years ago coming to a strict Protestant country, what would I tell the people in order maximize sin? The answer is exactly what Protestants hear today, that if you just have faith in Christ, you will be saved, your actions don't matter. This allows for self-righteous sin, where the sinners consider themselves saved and superior to others while they sin with impunity. This describes the average American today quite well. In such a case the "Christ" that they worship doesn't seem to have much to do with Jesus. So this is why the above quote seems to apply. Modern Protestantism is like Satan appearing as Christ and leading the people to sin.
(Note, I am not Christian but I attend a Greek Orthodox church.)
