Welcome to CI, Josh!
I doubt that you'll have much trouble here if you want to discuss valid matter for the Eucharist, but you will likely get some pushback quoting Faustina like you do in your tagline. 
Thank you Emile :)
I've had push back regarding St Faustina before... I'm fine with it, there is nothing one could say that I haven't heard before and if there is I'd like to hear it lol, only way to refine my positions and be sure. I've read some valid criticism and some not so valid criticism on that front... I still believe in the legitimacy of St Faustina and Pope John Paul II... I think Pope John Paul II made it in terms of Sainthood but there are certainly some valid criticisms of Pope John Paul II... I don't know if I should say Saint or not, seems to vary wildly among Catholics.
I mean, I too was surprised and upset to learn of that Assisi meeting and the Quran kissing, both bad and he should've been corrected on. I can see how one can err and I don't know all that was going on behind the scenes and the pressures he was under, I do believe his predecessor Pope John Paul I was αssαssιnαtҽd though (USA Church Committee 1975, Untraceable Heart Attack Gun), so there were no doubt many pressures on him and the tools and resources are infinitely better than in 1975... same with Pope Benedict XVI, I think they did the best they could or knew how given the resources available to them and the circuмstances they were under.
Furthermore, regardless of what one thinks of St Faustina, I think those versus in my signature are self evidently true and powerful, I've read similar form other Saints I just like the format from St Faustina's Diary the best.
