So, then are you saying that I can venerate Mary without praying to her and/or considering her in some way an integral part of the redemption process, and you will honor that position as one of those that is not settled by Scripture?
Other aspects of the veneration of Mary are solidly established by Sacred Tradition and by the Church herself --- which Jesus says has the authority, given by Him, to bind and to loose on earth and in heaven (Matthew 16:19).
A good Bible Christian is obliged to recognize the authority of Sacred Tradition and the Church herself. Why? Because this is verified by Scripture.
So the Marian veneration you referred to, is not an optional extra. It is a God-established part of the the Church via Tradition and the teaching of the Church herself.
