The ark is the earthly version of the heavenly.
Rev 11:19 And there was opened the temple of God that is in heaven; and there was seen in his temple the ark of his covenant; and there followed lightnings, and voices, and thunders, and an earthquake, and great hail.
But this is not to say that the ark which God instructed to build on earth to house the commandments is an image (idol), because it doesn't represent anything other then the very instructions of God himself. It wasn't as if the ark was designed to help worship Molech, or Zoroaster or something. It was designed as part of the whole temple veil and sanctuary.
Heb 8:4 Now if he were on earth, he would not be a priest at all, seeing there are those who offer the gifts according to the law; Heb 8:5 who serve that which is a copy and shadow of the heavenly things, even as Moses is warned of God when he is about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern that was showed thee in the mount.
The high priests were the only ones who ever actually violated the Torah in order to follow it. IPSEC, I am not sure where you are gathering your information about the deuterocanon, but the Tanakh is in tact as far as I know. There are no "fragments" of the Torah. Some of the other writings may be assimilated in later, but the first five, job, the psalms and major prophets are all in line with the Torah and testimony.
Isa 8:20 To the law and to the testimony! if they speak not according to this word, surely there is no morning for them.
Now Paul and others in the Greek texts, may in fact be committing heresy by preaching against circumcision and claiming that the Torah is annulled in Jesus' blood. The very idea of drinking "my blood and eating my flesh" that Jesus suggests is a violation of Torah itself, and a direct practice of Mithraism.
