“How can knowledge become clearer over time? Are we going to now know more about Christ and his teachings, 2000 years later, than the Apostles knew? That makes no sense? Do you know more about your ancestors than they did? Do you know more about what your great grandfather was thinking and doing than he did?”
A lot of protestants like to act as though they have not developed doctrine and blame the Church for developing pagan beliefs into Christianity. The argument is that the Catholic Church moved away from Christ’s teachings and developed a pagan form of Christianity.
Ask your friend to explain why prior to 1930, his beloved Baptist church taught the immorality of contraception, then after ABC became the popular standard changed their mind and now teach that it is morally acceptable? If this is not a development of doctrine, then nothing is. Previously, they taught contraception was a sin, now they teach it is not.
They may argue they didn’t have a teaching prior to 1930, but then this would be a development of doctrine that does not contradict their previous stance. The truth is that they did have a teaching; even though they were smart enough not to write it down so they could change it in the future and claim not having a teaching. It is quite genius in a way.
One has to give credit to the protestant tradition. They don’t write anything down definitively as a church, and will denounce the teachings of a member if they decide to change their mind later. They can say whatever they want and claim to never have changed because there is no history to check it against. They don’t have to agree with any Church Father, they don’t have to agree with protestant reformers, they only have to believe what they currently believe. If they change their mind, they will not have anything to prove what they used to believe. I love the line, “I only agree with person X in so much as he agrees with the Bible”. It doesn’t matter that person X uses the Bible to prove all of their claims because in the end, what is meant is “I only agree with person X in so much as they agree with my interpretation of the Bible”.
You can look into any protestant denomination and find changes in doctrine. Ask him who founded the Baptist church. Look up some quotes from that person and you are almost guaranteed to find some differences in their reformation founder and their current beliefs. The difference is, they contradict previous beliefs (as in the case of contraception) where the Catholic Church does not. We expand on a belief or definitively announce a belief where as they simply change what was previously believed and then try to deny history.
The fact is that our “development” occured in a few hundred years and is in line with every person before and not in contradiction to a properly understood Bible. Their development took 1500+ years and is direct contradiction to the Bible at any level of understanding at some point(s). Their beliefs contradict the Church Fathers and in a lot of cases, the protestant reformers. For example, Martin Luther and John Calvin both believed in the ever-virginity of Mary while most protestants today would not believe this. This is a case of trying to point out a spec in the Catholic eye which is not even there while they have a log in their own eye which make it impossible to see.
God Bless.
