There is a kind of ordering of Biblical Books... Beginning with the Pentateuch of the OT, and then the adding of the rest - It was the Jews who birthed Christ with their extended Bible, while the Woman at the Well [Photini], of the Samaritans, only allowed the first 5... Salvation came TO them, but not FROM them...
In the New Testament, the Gospels hold the position of Primacy, paralleling the Pentateuch, and then after these, the pastoral Epistles, then the General Epistles for all, followed by Revelation, this last never read in the Churches...
The Orthodox are not particularly concerned with the deutero-canon - Understood from the pov of the Orthodox phronema, they are entirely "Scriptural"... Understood as a matter of vocabulary, grammar, syntax, historical intent, and on and on, they can end up with real issues... But then, in that case, so does the whole Bible...
