Pope's Discourse at Close of Synod

I am, as so often, confused but intrigued and hopeful.

"Different opinions which were freely expressed – and at times, unfortunately, not in entirely well-meaning ways – certainly led to a rich and lively dialogue"

I would like to know who the Holy Father feels did not "mean well."
That's quite something, to impugn some Synod Father's motives.
I am curious to see if those that were appalled by Cdl Pell's little digs will react the same way to the Holy Father's.

"We have also seen that what seems normal for a bishop on one continent, is considered strange and almost scandalous for a bishop from another."

I would like an example of this.

"The true defenders of doctrine are not those who uphold its letter, but its spirit."

Again, specificity would help me to understand this.

"Human repentance, works and efforts take on a deeper meaning, not as the price of that salvation freely won for us by Christ on the cross, but as a response to the One who loved us first and saved us at the cost of his innocent blood, while we were still sinners."

So, not just there for the taking, but with repentance and "efforts"?
Or is the salvation freely won for us available without our repentance and effort?
