I don't mean this in an adversarial tone at all, please do not take anything I ask with any amount of malice or hostility. I just want to preface with that because religion is a very personal and deeply meaningful thing, and the internet is an imperfect medium to discuss it because you lack vocal context, facial/nonverbal cues, etc.
With that said, how do you square this with basically the prior 1900 years or so of Roman Catholic history? Really, prior to about the 1950s or so I do not think you could find a Pontiff who would speak so ecumenically about other faiths, in fact it would seem to be quite the opposite. Pope Leo says there is no such thing as a holy war, but does that not seem to be a very modern interpretation and in fact a direct contradiction to the words and actions of many other popes in the past? Same with the last few popes stances on the death penalty. For an institution that claims an unchanging infallibility, I sense a lot of change over the past 60 or so years coming out of Rome.
For context, I was once Catholic but now have a rather complicated relationship to it. One the one hand, I find much I just simply do not agree with and cannot abide in it, but on the other hand I'm very much haunted by it and find myself continually drawn in by much of its art, aesthetics, and even elements of its theology. For what its worth, I am very compelled by the figure of the Blessed Virgin and on occasion will still throw an Ave Maria her way.
I add that only so you know I ask my questions because they are things that I myself have struggled with and have yet to come to satisfactory answers on.
