Hold on there plainswolf… the 153 connection, while nice, is not a necessity for either dogma or discipline. Rather, it is merely devotion and that is something that can be changed.
There is no mandate that you must recite the Luminous Mysteries in your rosary devotion. It is merely a logical, practical expansion on the life of Christ. And, my deer plainswolf, that is the entire point of the rosary – to meditate on the life of Christ. The point of the rosary has nothing to do with Fatima in the strictest sense, nor a quasi-protestant numerology scheme devoted to 153. While those accidentals are nice, they are not absolute musts.
If you do not wish to recite them – do not. If you would like to meditate on more of the life of Christ – then do. But, please, don’t lecture us (with exclamation points and admonishments to read a calendar for emphasis mind you) about Fatima and the days associated with it. The beauty of the rosary is that it brings one into meditation on the life of Christ, which gives us a chance to reflect on our own salvation. You are not required to recite them if you don’t want to… just return the favor and grant us the ability to broaden our meditation without a ‘protestantesque’ numerology or out of the norm Fatima connections.
Your best point, however was the one regarding the origin of mysteries we celebrate. Yet, even that is not binding. For goodness sakes the Franciscans and the Servites both recite a differnet rosary than the one you have espoused. Does that make their rosaries invalid or some other such thing since they do not fit into the numerology of Fatima? I don’t think so.
