Um...calling someone "ignorant" multiple times, as well as "lazy" and also intimating they were terrible parents is NOT negative?
One could argue, perhaps, as to it's truth in a particular situation or not, but there is no way under logic, reason and basic understanding of English language that the sort of words you used were not negative.
And IF you have read scripture, as you suggest every Christian has to come to themselves, then you must have read how it is the responsibility of pastors, teachers and leaders to point to correct Christian living. In which reality does this not involve bible reading? To suggest that Priests don't need to point parishioners (or whatever their called in the RCC) to reading scripture and to know God's word intimately, is a failing on their part, not just on the individual Christians part. After all, people can only come to the truth of the gospel from hearing. That puts the onus on the preacher first...if they don't point to the truth, who will? If the Priest constantly advised his parishioners to study and read scripture, and they didn't, THEN it would be on them. But to be led to believe that following the 'church' traditions of attending confession, praying, going to mass, etc, would be enough, the RCC is, even inadvertently, doing a disservice to many....or, at least, the particular parish that Grams attended was.
Sometimes people assign blame to cover up their own short-comings...but sometimes people are wronged. It's a fallen world, and you can't deny that people are doing other people wrongs all the time. Are we to place those wrongs upon our own shoulders as well? Not really, that would be making something up, dismissing reality. So is your problem that it took Grams years to find a true, close relationship with Jesus...or are you complaining that it was, apparently, the RCC that got in the way of that? For whatever reason. Because if it had been some bogus Protestant denomination...like one big on the health/wealth "gospel"...I don't think you'd have a problem and you would claim she's whining about a thing. Just because you may have had a wonderful experience with the RCC, and your Parish is bringing you closer to Christ, and encouraging you to read scripture, that doesn't mean that all Parish's are like that; that all Priest's are like that. You might ask Grams about her bad experience, and sympathize that she'd had to change denominations to find that relationship, rather than enforce for all to see, that she made the right decision.
