St_Barnabus,
Yes, and I am a example of one such person who remains unconvinced.
However, I will say that my extensive discussions with Catholics on CAF (you have mentioned my posts there) have had a profound impact on my life and my beliefs. When I joined CAF in 2009, I was still officially in the Baptist Church. If you were to read my 4,000 plus posts on CAF (I wouldn't recommend it
); you would see that many of those posts read like a diary of a spiritual journey, as I noted in this
CAF Post:
"As you know, I have been working through my journey very openly on these forums. Discussions here, combined with prayer and study, lead me to embrace the Sacraments, infant baptism, the Real Presence, the Communion of the Saints, the Assumption of the Blessed Virgin Mary. I have released Sola Scriptura, salvation by faith alone, and salvation based solely on the "sinner's prayer." Considering the fact that I was a Southern Baptist when I joined this forum in May 2009; I'd say I've proven that I am willing to change long held beliefs, if I can't support them. . . ."
Same sentiment posted here.
As someone who knows that most Baptists are staunchly [not always but usually] against the sacraments and the Church - i feel you have made great strides in this break-through.
The thing i hope for you is to let go and embrace there is one Church and though man may have tried to dishonor the Pope - or rather St Peter's Chair - the Bible is key to knowing Papal Infallibility does exist. The question is really - what does it actually mean?
It does not mean he is right all the time, or is perfect - but rather it means when teaching the Church he cannot err - because the Lord promised the Church would never teach heresy as He handed him the keys and specifically to Peter whom He gave the keys in front of them all and told them -
the Father chose Peter - and the evidence was the words our Father put in Peter's confession.
[Only the Lord can dispel such graces and He too can shut up the mind so we are confused]
And aside from that - Jesus also told the Jews to follow the Chair of Moses [while He was alive that is for He had not yet established His Church without fulfilling His mission] and not do as they do who sit on the Chair - but obey that Chair.
Knowing these things are important to the Lord - and how He was setting up their importance for us - we should consider the historical writings even in the beginning - some subtle - some not so subtle - regarding the Chair of Peter and it's significance to the Whole World [Church].
Like all things - not everything was written at the beginning - but inferred. As you were led to see the sacraments. Though the words sacrament, Trinity, Incarnation, Hypostatic Union and so forth werent dialogued in the Bible nor even in history until it was necessary - the same is true for the importance of the Chair of Peter. Though it was certainly inferred and in their time and language sometimes - spoken outright as well.
But going back to the Bible:
"Peter, feed My sheep." and "...Peter, feed My lambs." But also 'Confirm thy brethren...' which means 'teach' the others.
Yes, Peter was teacher of the whole Church even his 'brethren' which were the Apostles.
As teacher - and the promise given to Peter that the gates of hell would not prevail, which means - heresy would never be taught - we can fully and absolutely trust Jesus and have faith like a child in the Chair of Peter or - we can resist because the flesh may chose not to believe such a thing is possible even at the words of the Lord.
Just some things to think over.
And fwiw - i congratulate you on your journey. Good job so far. Keep up the good work.
