Hi, in fairness you are misreading the intent. I was simply addressing the point that the Anglican position on the Deuterocanonicals namely that they are helpful and good for instruction, however whilst they can be used to support a doctrine, for a doctrine to be seen as essential it must be able to be demonstrated from the Canon Proper, and it is certainly valid, and indeed helpful to support that further from the Deuterocanonicals. No one is saying, and no-one said anyone said that the Deuterocanonicals contain everything necessary for salvation.
In another discussion I demonstrated a point using these passages
Numbers 21:8-9
And the Lord said to Moses, ‘Make a poisonous serpent, and set it on a pole; and everyone who is bitten shall look at it and live.’ So Moses made a serpent of bronze, and put it upon a pole; and whenever a serpent bit someone, that person would look at the serpent of bronze and live.
John 3:14-15
And just as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life.
Wisdom of Solomon 16:7
For the one who turned towards it was saved, not by the thing that was beheld, but by you, the Saviour of all.
Whilst Numbers and John make sense the passage in John is better understood when you include the witness of the Wisdom of Solomon, which most scholars believe was intended by the author.
