If, as you claim, Catholics wrote the Bible, why don’t you use it for the immaculate conception? Because you can’t. So you proceed to divert from the issue. Catholic encyclopedia admits you can’t justify this false dogmas with scripture or “tradition”.
You wrote: ‘Catholic encyclopedia admits you can’t justify this false dogmas with scripture or “tradition”.’ Where does that website say that? I see it says no direct reference in Scripture, but we admit that is true.
My statement was “Catholics selected the writings of the Bible.” The point was that if you hold Scripture as infallible, you are holding a part of Catholic Tradition infallible. Which is what the teaching on Mary is too - a result of the inspired teachings of early Church fathers and beyond.
You may choose to discount this Tradition and to not venerate Mary, or even dishonor her. But do you desire other people to pray for you? Do you believe in Heaven? If you answered “yes”, who is the person who can pray for you that is closest to The Christ? Mary.
