Imagination and fantasy must then also be “dangerous” when reading “Scripture” as with the Divine Office, for word for word that is where the “mysteries” of the Rosary reside, as do the Psalms. Seems to me your left to explain anothers thoughts which seem to lack logic in retrospect.
If the Liturgy of the Hours are more beneficial, is not of topic in this thread, the Rosary is. A comment as such suggests all should pray the Divine Office instead, highly unlikely. If the world prayed the Divine Office daily then we wouldn’t have a need to discuss the Rosary. If one cannot in time management devote 15-minutes daily to the Lord, then you’d be hard pressed to convince me you will pray the Divine Office.
The history of the Rosary is well documented. We are talking about the Rosary as known to the world today. Just as the Divine Liturgy developed over time, so did the Rosary.
