Kolokotronis in 14 also noted, correctly, that the choice of words is not the best, as we associate merit with an exchange transaction, when salvation obviously is not. However, here "merit" is clearly put in the context of lifelong faith and charitable works; the sovereignty of God in granting salvation is clearly stated. The statement is consistent with what the Church has always taught, that robust faith and works of charity are necessary for salvation.
"The statement is consistent with what the Church has always taught, that robust faith and works of charity are necessary for salvation."
To the extent that one understands that the works of charity are not some payment to God or for the piling up of merit but rather because charitable acts, properly undertaken, allow us to die a bit more to the self thereby becoming more receptive to grace which in turn leads to more "works" which lead to more dying to the self, which leads to becoming more receptive to grace, etc.
