Actually back then, there were no such things as school. And basically Jesus learned the scriptures [in human form as He developed] thru His Mother.
Another reason He created her as He did.
Once taught, I am sure He knew them.
Remember He lowered Himself lower than the angels to become man, and to be fully man [ and God] He was taught as a child.
So He would have everything we had.
But assuredly, altho He was taught the scriptures, He knew what they meant - whereas only outside of Himself did His Mother understand them.
I will say I agree with your summation on NOT using sola scriptura....because honestly, the reformation borrowed much of Tradition.
Altho the further we get from Luther's day, the more we see less Tradition being used.
Example; JW's deny the Divinity of Christ - based 'solely' on the scriptures.
NOW - would you say their interpretations are as valid as someone else's ?
In fact JW believe Jesus is St Michael the Arch Angel because revelation says 'with the voice of an angel'.
[DOnt aSK ME...]
Anyway, the Trinitarian belief came from [drum roll please] the councils of the Church.
Hypostatic Union came from the councils of the Church.
The Incarnation came from the councils of the Church.
So you see, altho the 'allusion' of the truth can be found, no where does the scriptures tell us with uncertainty that the Trinity exists.
So you see, altho Tradition is vehemently denied, it is still used. So it's a question of what Tradition some keep and take with them, and which they throw out.
Its context... it really is.
And the only way we know anything today was brought to us by...[ring the bells]
The Church.
Protestants wouldnt exist without THE CHURCH.
God Bless.
