Hi Luke,
I am fairly caught up though it was more of a skim.
It I did not notice in the reading if you mentioned which denomination your parents left the church for? It would be helpful to know because in our explanations, it is helpful to know if one believes in OSAS or can lose their salvation. That kind of thing.
As for your question about Mass, most who make the claim that the Catholic Church was corrupted, usually believe it happened sometime before 300AD. Constantine is the usual suspect who is pointed at.
I would first address this claim. I stand on Scripture.
We see in scripture, that there will always be God’s Church. And we can see that the Church will never fail.
There are many scripture verses I could cite. Things like Matt 16:18 in which the gates of hell will not prevail; John 14:16 which tells us the Holy Spirit will be with us always.
But my favorite is this one.
1Tim 3:15 if I am delayed, you may know how one ought to behave in the household of God, which is the church of the living God, the pillar and bulwark of the truth.
If the Church became corrupt in its teachings, how can it be the pillar of truth? Either something is true, or it is not. To think that the Catholic Church fell into error in teachings (not error in actions, there are plenty of sinners in the leadership of the Church throughout the Ages) but error in the what it taught as officially true, how can scripture still be true?
It was the pillar of truth, started to crumble and then God brought the reformation, and transfered His church to Protestants? In scripture we can see where Christ transferred the leadership to His new Church with the New covenant. We also see in scripture that it warns us of those who will come along teaching falsely. Where in scripture do we see the transfer of authority to Protestants and who came along Protestants or Catholics?
As for what the Mass looks like, it depends on how you mean. In early Christianity, they worshipped in houses, things were secret for fear of persecution. The Church grew. It became legal to worship as a Christian, Churches started to spring up. And glorious churches, decorated for the glory of God became the norm.
So what exactly are you referring to when you ask about what it “looked like”.
And do you believe that something can change in appearance but still be the “same”? For example, can a tree grow from a sapling into a old growth tree but still be a tree? Have the changes in the appearances of the tree changed the basic fact that it is still a tree?
God Bless,
Maria
