Dear Kathleen,
Thanks for your questions – all good ones!
Since you are currently in RCIA, you have much to learn about the Catholic Church in general, so maybe those in charge of your program are trying to “lay the groundwork” before doing too much teaching on Mary. Some programs do that. The Catechism of the Catholic Church makes it clear in paragraph 418 (Part I of the Catechism on the Creed):
487 What the Catholic faith believes about Mary is based on what it believes about Christ, and what it teaches about Mary illumines in turn its faith in Christ.
When one uses the term “consecrate” one means to set aside for a special purpose. So when a persons says “I’m consecrating myself to the Immaculate Heart of Mary”, they simply mean they are desiring to draw closer to her, and in the Catholic Church this includes a desire thereby to draw closer to Christ. Jesus was conceived in Mary’s womb by the power of the Holy Spirit. Mary was chosen by God to bring Jesus into this world in a physical way. The Word became Flesh to save us. Our Catholic Faith is “Christocentric”. Mary, however, has been given to us by Jesus on Calvary and we honor her as our Mother and Model.
You may have noticed some threads on the Forum on Consecration to Jesus through Mary. This is a beautiful practice begun by St. Louis de Montfort, but there are also simple prayers of Consecration by other saints that are approved by the Church. Why would you or anyone want to consecrate themselves? It is really a matter of the heart, it seems to me. I believe God gave me a strong devotion to Mary after I learned to love Jesus and all the Church teaches, and that may be what you will experience or are even now beginning to experience. Take your time, however, and let the Holy Spirit continue to bring you into all the beautiful Truth of the Catholic Faith.
I hope you have a good leader in your RCIA Program, and perhaps you also have chosen a good Catholic sponsor who is also available to answer questions. If you have a copy of the Catechism of the Catholic Church or the Compendium of the Catechism they are also great helps to growing in the knowledge and love for the Catholic Faith. I’ll give you links to both:
Catechism of the Catholic Church - This second edition is best - the glossary is a great help in back of book to explain unfamiliar words. You can use the Index to find much good infor on Mary too.
Compendium of the Catechism - this is a shorter version done in Question and Answer format. My husband and I used it when we were in charge of an RCIA group. The persons in the RCIA Program found it to be a great help, as well as the full Catechism.
PS You do not need anyone to pray with you, when you wish to pray any Litany.
