Knowledge is but hearsay until it is in the muscle. The doctrines and dogmas are valuable, and necessary to discuss at times. However, the Christian faith is a life lived more than it is a fact learned. St. James tells us this in no uncertain terms in his letter to the Church. Rather than pilpul about exactly what he means by "faith" and "works", consider actually attempting to free ourselves from sin and helping each other in this endeavor.
Talk to each other. Talk about virtue, and how to sow the seeds of righteousness in your lives. Whatever is pure, righteous, holy, dwell on these things.
Confessions can be made to your priest, and indeed are better made to your priest than to an imageboard. And as my priest told me when I bemoaned yet another lustful relapse, thinking about your addiction, even in hatred, will only drive you to it. Our God is light, and in Him the is no darkness at all.
Christ is truly risen! Blessed paschal season to you all.
