Thank you for visiting our new Marriage & NFP website for the Roman Catholic Diocese of Phoenix. We built this website to help engaged couples prepare for their wedding and a life-long Catholic marriage. You will find a significant amount of resources and information on Natural Family Planning (NFP) on this website to help you have a successful and vibrant Catholic marriage.

What is Natural Family Planning (NFP)?

Modern Natural Family Planning is 100% natural and up to 99% effective as a family planning method. You will also learn how NFP benefits a couple’s relationship, one indicator of which is the nearly non-existent divorce rate among NFP-practicing couples.
