I will probably not be too popular with this answer, but yes, I do believe that some people, some of the time, can and
DO go way overboard with their devotion to Mary (or any of the other saints for the matter.)
Do I think that is common? NO
But it does exsist. I was told I was not “Catholic” if I did not pray the Rosary exactly as it was given to us by Mary at Fatima. I have been told that if I do not pray the rosary, God will not hear my prayers. I have been told that without Mary’s intercession, there is NO WAY I can ever acheive heaven. And I have been told that I, as a sinful human being, have NO RIGHT to approach God or Jesus without going through Mary first.
All of these things came from a group at a parish I was involved in. It turned a lot of people off, and eventually the group was “disbanded” as an “official” ministry of that parish. A couple of the more “hard-core” members used this as an excuse to stop attending Mass because the pastor “hated Mary”, which, of course, was not true. What he was seeing, and tried to correct, was a series of very serious misunderstandings about the Blessed Mother, and he was met with nothing but resistance. Some people will believe only what they want to, no matter how misguided or wrong they are.
All of that being said, I am very happy for all of you who have such deep devotions to Mary, and that you have seen the graces that come through that devotion in your own lives. I do not have a very deep devotion to Mary, and have never had one. It does not mean that I do not have a very rich prayer life, or that I see Mary as unimportant. It means, that, for me, I don’t find any particular reason to go through Mary, I have a wonderful relationship with Jesus, and feel very comfortable going straight to him, or his Dad!
The best advice I ever received-
Pray as you can, not as you can’t! What matters is that you pray!
