About Fiat90

Fiat90 is a 90-day Catholic program designed to draw women closer to Christ through prayer, self-discipline, and growing in virtue. Rooted in the inspiration of the Virgin Mary’s fiat, her wholehearted “yes” to God, the program encourages participants to imitate Mary’s virtues through a lifestyle of prayer, fasting, self-sacrifice and fellowship.

Our Mission

To guide women into a deeper “yes” to God’s Will, modeled after Mary’s perfect fiat, in her humble and courageous surrender to His Will. Through prayer, simplicity, and community, this 90-day journey invites participants to strip away distractions and rediscover the beauty of living fully in Christ. Through daily disciplines, fasting, and spiritual reflection, women are strengthened in cultivating virtues of faith, humility, and devotion in the midst of their daily lives. FIAT90 is not a pursuit of perfection, but a walk of grace and an invitation to echo Mary’s words: “Let it be done unto me according to Thy word.”

Hi, I’m Lydia Zelinski!

CEO of FIAT90

I’m one of the co-founders of Fiat90, and have been leading the program for the past five years. This journey has drawn me closer to Christ and opened my heart to the beauty of community and shared faith. Each year, I’ve learned anew what it means to live Mary’s “yes”, through surrendering, trusting, and letting God work in the quiet places of my life. My hope and prayer is to continue growing in and following God’s Will for Fiat90, wherever He leads.

Where It Started

On Holy Thursday in 2019, after completing the Seven Churches pilgrimage through the beautiful historic churches of downtown Buffalo, NY, we found ourselves sitting together in a parking lot in front of a Panera Bread. We shared how we both were searching for something that would draw us closer to Christ while also deepening our friendships and sense of community. Having previously done a co-ed version called Nineveh90, we knew this new program needed to be female-focused, especially since a version already existed for men through Exodus90. As we prayed and talked about what God was asking of us next, we came up with an acronym: FIAT — Faith, Integrity, Accountability, and Truth. Over the following months, we drew from our past experiences to create practices that would help us grow in grace, strengthen our relationship with God, and live more fully as women of faith. We hope and pray this program blesses each of you!
