I could not agree more.
The consequence is that not every Tom, Dick, and Harry is fit to do, ought to do, or wants to do theology. But when they want the autonomy to decide matters best left to theologians there is a problem.
Nobody has to understand what happens at the Mass as well as Aquinas does - UNTIL they set up shop on their own and claim be be selling an understanding better than that of Aquinas. If they can't back it up, if they don't think being able to back it up is their call, then how can they say theirs is better or ours is wrong?
And, in the case, say, of the cult of Mary, when those who are not theologians express their love of her, we cannot require that they do so with theological precision. And yet the knives come out when somebody says something theologically incorrect but no more wrong that it is wrong for a mother to say to her baby, "I adore you," (which, by the exigent standards of many non-Catholics would be blasphemy.)
If understanding is not what one claims for a call, then there is no obligation to "[get] lost in the volumes of explanations presented and the literature one must read for understanding Romes rituals and meanings."
BUT then one cannot pretend to understand whether they are right or wrong.
You can't have it both ways. Either attack us theologically and be prepared to engage in theology, or leave us alone. Do not pretend to mount a theological argument and complain if you are met with a theological reply.
God is simple. Loving God is simple. TALKING about it is complicated and difficult.
