I did read the chapter that you asked. And as Solomon learned the hard way (and we should take his lessons to heart) I found it all 'vanities and vexation'. In my humble thoughts, and they are humble, I never got past 11th grade), I'll start with the title of the book "The Great Ecclesiastical Conspiracy". The word 'Ecclesiastes' is from the Greek, meaning a gathering or assembly. When I read Solomon's book, I take it to mean 'a gathering of what he has learned' or 'an assembly of his trials and errors wrote for the benefit of our learning'. (*sigh, not that we did) 'conspiracy' is taken from that dead language mentioned, Latin; and as close as I could find means 'to breathe in harmony'. Fitting. Taking that meaning to heart, I prefer to 'conspire' with my Lord Jesus. And for that learning, I have to turn to my Bible. And I'm not going to worry myself over someone interpreting the word(s): Gathering, Assembly, Congregation; into the word 'church'; or the word 'elder' into the word 'priest'. These are mans folly and mine too, if I fall in it. And here I'll tell you that I almost did and learned from it, thank the Holy Ghost. OK, I know that you're not asking for a sermon. I read your profile and know that you are very educated and know these things. To your questions:
1. Did the Roman Catholic church conscientiously try to hide the Bible from the people - and if so what might have been their motivation?
I'll direct you to another article concerning the KJV:
http://ngm.nationalgeographic.com/2011/12/king-james-bible/nicolson-text. The article is secular, just as the one you read, but a bit more unbiased. At least in my opinion. This article suggests that the language (English translation) of the Bible was meant to be accessible to all people. I particularly focused on the old cowboy who was saved while in jail because of this Bible.
I do think that the RC church has motivations of their own, to protect their 'hierarchy' most likely. Man is full of vain-glory. We love our traditions and ceremonies. And that would go for all recognized churches. (the whole of Matthew chapter 23 is a good study) Jesus clearly stated in verse 3: All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say and do not. And I'll take this with 2 Timothy chapter 3:16-17.
As for your thoughts: I agree with all my heart your definition of religion. Religion has disappointed me all of my life, tangled up my thoughts and served more to pull me away from Jesus than bring me to Him. I am happier in a relationship with Jesus. But again, I need my Bible to grow. (refer back to 2 Timothy) ~ And we do need fellowship with one another, in Christ.
Man has attempted to intentionally interpreted God's Word to suit himself and no where in scripture can you justify the present church. That's a dog chasing his tail. No matter how much man might try to justify himself using Scripture, he can't; we will all be judged the same in the end. We must work out our own salvation, each of us; by understanding God's Word as it is. For that I need my Faith and my Bible. My salvation is not going to be given me by any church. It will go terrible for those that mislead His children, but it will still go terrible for His children if we allow ourselves to be mislead. God is no respecter of persons.
Are we doing 'church' wrong? If we're 'doing' church, then yes we are. The True Church, The Body (assembly, gathering, group, herd, bunch, flock) of Christ will not be confounded at the end. Jesus is the True Vine and the Only Way, we build on Him, the Rock. Not even the individuals within the Body using the Gifts of the Holy Spirit, those individuals are for our edification, part of the vine, but not THE VINE. They can minister, but they don't save us.
All Scripture is God Breathed, I do not think for a minute that God would allow His Word to be 'lost in translation'. Man's knowledge is foolishness; vanities and vexations. Jesus is Wisdom. If we take the Bible as a 'whole work' go back to the original sin, God's first commandment to man was not to eat the fruit of the tree of knowledge. We've gone downhill ever since and are still eating it.
I love to study and am interested in history, I read just about everything I see when it concerns the Bible. But I always keep in my heart and mind, my Bible; first and foremost in learning. And I trust my Lord to give me understanding.
Thank you for this discussion! I hope it helped in any small way.
