​ABOUT

1 FLESH is a video-based course designed to help couples understand and embrace Natural Family Planning (NFP) in light of Catholic Church teaching. Through 28 thoughtfully crafted videos, the course offers clear and accessible instruction—rooted in truth, guided by faith, and open to life.

Rather than teaching the methods of NFP, 1 FLESH focuses on the why:
​
– Why the Church upholds NFP
– Why it matters for your marriage
– Why it’s worth embracing

​Natural Family Planning is based on a woman’s God-given fertility cycle. By learning to read the body’s natural signs, couples can either postpone or achieve pregnancy without artificial interference.

Unlike contraception, which blocks or suppresses fertility, NFP works with the body’s design and honors the dignity of both spouses. It reflects the Church’s vision of love as a free, total, faithful, and fruitful gift of self.

​Whether you’re preparing for marriage, already married, or teaching others, 1 FLESH is here to support your journey. Created for individuals, couples, and instructors alike, it’s a free resource to help you live out the beauty of God’s plan for love and life.
