I love this topic!! It is just amazing how many people get married without really knowing what marriage is all about. My husband I went through the pre-cana weekend retreat 5 years ago and we loved it!!! We also had 2 couples,one who was married for a long time and a newly married couple. The experiences they shared was unmeasurable. The older couple is actually the Directors of the NFP program in our diocese and they shared a wealth of information on that! (critically important to marriages). I think one of the most important things we got out of it was how to communicate better and really listen to each other. We loved the journaling part of it a lot. We also read several Catholic books on marriage, the two I would suggest that are pretty easy reading are…Marriage is For Keeps by John Kippley and Marriage a Path to Sanctity by Javier Abad and Eugenio Fenoy. My husband and I both had a copy of these books and read on our own and then would discuss them when we were together. I think what surprised me most was how many engaged couples there had no idea what the churches teachings were on marriage, contraception and so forth. I wish more Christian churches required some type of marriage preparation before letting couples marry, maybe we wouldnt have so many divorces. Best wishes and prayers to each all of those engaged couples out there, and remember its not about the wedding, its about the marriage. Enjoy your day, it goes by so fast and then really enjoy your marriage, it is truley a path to sanctity!
