I was consecrated this past December 8, the Feast of the Immaculate Conception, a Thursday, after having confessed on the prior Saturday, the 3rd.
As an aside, my daughter also had a funeral Mass and was buried on the Feast of the Assumption, August 15, 1996. The Church was not supposed to do funerals on a solemnity or a day of obligation, but Our Holy Mother intervened.
Regarding the preparation, because of my schedule, I planned about 45 days of preparation instead of 33. I wanted to pray in earnest and not just say the prayers for the sake of saying them. So I took 45 days to prepare and was glad I did.
Some of us from our parish went to the Monastery of Our Lady of the Holy Spirit in Conyer’s Georgia where one of the monks, Fr. Anthony Delsi, held a “Consecration Day.” He celebrated Mass, during which we read and signed the act of consecration, and then placed the act of consecration on the altar for the Liturgy of the Eucharist. Two of us were newly consecrated, and about five others renewed their consecration.
A Fransciscan Priest now in Brazil on a mission, had recommended consecration to me, and suggested that the best translation of St. Louis Demontfort’s book was “True Devotion to Mary with Preparation for Total Consecration” as published by Tan Publishers.
Since then I have purchase “God Alone” which is a collection of the Saint’s writings.
I would recommend not rushing it, not trying to just get it done, but instead getting a copy of True Devotion to Mary, Preparation for Consecration, and a copy of The Imitation of Christ by Thomas Kempis if you don’t have it - he preparation does include reading select chapters from Imitation of Christ. If I had to do it over again, I would take four or even five months. I would read The Imitation of Christ, then True Devotion, then I would reread True Devotion slowly while I did the preparation over a 60 day period.
Personally, I am going to repeat the process slowly again either this spring/summer or though the fall.
I wouldn’t rush it or do it last minute. As JohnPeter stated, the material is a bit heavy, not at all similar to modern writing. It takes time to get through. Spiritually, you are giving your entire life to Our Holy Mother as a slave. You are giving up all of your merits and good works, which would normally apply to your own salvation - giving them to Mary - for her to use and distribute for the sanctification and salvation of others as she sees fit. This is not something to enter into lightly, and it is something that grows within me every day, now only two months out.
Take your time. Get the books. Read slowly and pray, pray, pray… God will wait. He is patient.
