Hello I am a roman catholic who has been investigating eastern orthodoxy (as well as the church of Christ - Bible-only church) for some time. My experience investigating has been mixed - some positive - Fr. Peter Gilquist has been encouraging and negative - some have been less receptive to a potential convert. I began questioning roman catholicism on questions such as papal infallibility, primacy and the filioque and all this was exacerbated by the priestly sex abuse scandal. I grew up in Boston and knew a number of players in the scandal. As an aside, the funny thing growing up is that we all were mostly Irish Catholic but had one large orthodox church where a handful of our friends went. There was a sex abuse scandal there with one of the "married" priests so it was known to stay away, etc. - all the while the widespread abuse was going on in the rc parishes!
Being a grown man and father of a large brood, I desire the best possible form of worship pleasing to Our Lord. The church of Christ (Bible-only) does not believe the Eucharist is the real Body and Blood of Our Lord so I pretty much ruled them out (although the democratic part of all "brothers" together in Christ, no titles, etc. appeals to me). I know the rc positions on primacy, infallibility and the filioque. What are the positions of the early church fathers, tradition, etc. on this primacy, infallibility and the filioque and how/when did the rc church depart from that (if i fact they did)?
Thank you in advance for any assistance.
