Hmmm . . . praying is quite obviously recommended in the Bible. And the prayers of the Rosary are direct quotations on the Bible. To pray a Hail Mary is to reflect on the Incarnation of Christ. The Incarnation is, along with the Trinity, the central doctrine of Christianity.
And why is the focus of my faith not firmly, 100%, always on the One who the whole book is about?
If you think that the Rosary is not focused on Jesus, then you're not familiar with the Rosary as it was taught to me.
And where dows it say anything about Mary being sinless?
Luke 1:28.
Or not dying?
The Catholic Church does not hold as an article of faith that Mary did not die. Please cite a reference for this assertion.
Or having ANYTHING to do with my fate?
She's the mother of your Savior. I'd say she is inextricably entwined in your eternal salvation.
And why if anything were we not asked to pray to Christ 50 times?
The Church asks us to pray to Christ every day. The Church asks us to call upon His Name every time we are tempted - unless you live in a padded cell, that must be hundreds of times each day for a normal person. The Church asks us to read the Gospels every day. The Church asks us to imitate Him every day. Apparently you've never read any Catholic catechism ever in your entire life, or you'd know that pretty well. I find it hard to believe you've ever been to a Mass.
Some of the same reasons I am no longer a Catholic - I can read the Bible for myself, and belong to a church that meets and governs by the rules I can also read and understand for myself.
Why do you take the Bible as your only source of religious authority? If you can understand the rules so plainly, why does every Protestant denomination interpret the rules differently? Where did you learn to read Hebrew and Greek so well that you are able to so authoritatively read the Bible for yourself, instead of taking some human being's translation for granted?
