I was raised Catholic and when I went to sunday school there really wasn't a lot of bible study being done, it was more memorizing prayers. It may be different now. When I grew up and started studingy my bible I realized there were scriptures that contridicted the catholic church in how it is run - as far as you shouldn't call anyone Father except your Father which is in heaven and the wearing of the collars and a lot of the rules that they bind are not scriptural.
From what I read it is best to go to a church that does not have their own creed book but goes solely on the bible. I did like the worship part of the catholic church it was very ceremonial which gave you a feeling of awe but it was also very repetitiions. My Mom went to Catholic school all her life and rasied us 7 kids catholic but now she is actually going to a christian church. She did teach us all to belive in God and I do believe that the Catholic Church does believe in God, I just think they need to go back to just the bible.
There's nothing wrong with repetitious prayers. Our Lord prayed the same prayer 3 times in the Garden of Gethsemane. And indeed, throughout the world many Christians pray the Our Father. The key is that they cannot be VAIN repetitions. There are people who see the prayers as a sort of magic formulae and that's what Our Lord was cautioning us about. But as long as the prayers our said with a humble mind and contrite heart Our Lord will accept them.
In fact, in the Eastern Church one of the oldest and most repeated prayers is as follows. "Lord Jesus Christ, Son of God, have mercy on me." It's often said hundreds of times in a row.
And as far as not calling anyone Father, that's an example of hyperbole, exaggeration to make a point. If we look at the context of where He's saying these things it's to point out the faults of the Pharisees who set themselves up as the ultimate spiritual authorities and forgot that they got their authority to be spiritual fathers/teachers/masters from God. If we insist on a literal translation then we have to toss out the words "Master" and "Teacher" as well. But obviously from the scriptures we can see that Our Lord was speaking in a hyperbolic sense since there are several examples where the apostles call themselves with the term "Father"
Paul refers to Timothy several times as "my son" or "my faithful child" He also calls Titus, "my true child in a common faith..." and he even says, "I appeal to you for my child, Onesimus, whose father I have become in my imprisonment" Obviously we can't say that Paul was in error here can we?
And it wasn't just Paul. Peter writes, "She who is at Babylon, who is likewise chosen, sends you greetings; and so does my son Mark"but we know that Mark wasn't his biological son, but rather, a spiritual son. The Apostle John repeatedly writes about "my children" in his letters and even refers to a group of the leaders as "fathers" in 1 John 2:13-14.
As I mentioned before, I've yet to encounter a church community so in love with the Scriptures like the Catholic Church. It's still amazing to see it.
