I only have to ask one question?
How old is your Church?
The Catholic Church was founded by Christ on the Apostles, the first bishops.
If you choose not to believe and belong to a church founded much later, that is your perrogative.
Jesus IS the founder of the One, Holy, Catholic, and Apostolic Church.
Can your denomination lay claim to those Marks of the Church?
Define "how old is your Church". I guess it's as old as where the Bible starts - "In the beginning God created the heavens and the earth."
Being non-denominational, I use the Bible as my guide; nothing more, nothing less. The age of the "religion" isn't as important as things like, “Again, truly I tell you that if two of you on earth agree about anything they ask for, it will be done for them by my Father in heaven. 20 For where two or three gather in my name, there am I with them.”
I believe God is the Founder of my Church and it includes the lessons of the Old Covenant and is nicely adorned with the crowning glory of His gift of Jesus which set the wheels in motion for the New Covenant.
MY belief in God as the Great I AM, and my Creator, and in Jesus, The Sacrificial Lamb of God as my Savior, makes my lack of a denomination perfectly fine.
You point out another foible of religion/religious institutions - they claim the same Christianity, yet they each lay claim to their brand as the best brand. 30,00 plus sects of Christianity can only be right in one thing - Christianity. Where in the Bible, does it mention "Catholic/Lutheran/Baptist", ad infinitum?
I respect the institution of the catholic Church, but I also believe, like any man-determined institution, run by men with varying opinions, it has flaws. I concede it has probably reached more souls than any other sect, but I fail to understand the pomp and riches that it hoards and the way it reveres its Priests/Bishops/Popes - many of whom have appeared to be apostate and who have spread their opinions into things like global warming and have committed crimes against the youth they have been entructed with. Add men to the mixture and you must ad flaws.
I do not expect perfection from Men, but I do expect the focus to remain with God, Jesus, and the Holy Spirit as laid out in the Bible - no more, no less. Jesus told the disciples how to pray - He told them to start out with "Our Father", not "Virgin Mary, or "Saint Peter". I prefer simple instead of a host of "holy sacraments" and other rites and rituals that are offered with a mystic that is not necessary since Jesus decided to develop a personal relationship with Men that tied us to a personal relationship with God.
I hope I have answered your question - Christianity trumps religion. Period.
God Bless - you do good works carrying the Word - don't let my "pops" distract you from that - use them to strengthen your own faith. I use these little exercises to evaluate and do some more studying which I find beneficial.
