The crisis in Masculinity
.avif)
Masculinity in the modern age is at a crisis point. The hearts and souls of men are not only being starved, but systematically cramped, shackled, and destroyed.
Young men are tyrannized by safety and emasculated by comfort - and exist in an isolated social desert, void of support, mentorship, and purpose.
Sebaste seeks to fill this void as a fraternal organization by building up men through transformative adventures, physical challenge, and raw exposure to the transcendent power of truth, goodness and beauty in themselves and the world around them.

“The world offers you comfort, but you were not made for comfort. You were made for greatness”
- Pope Benedict XVI

Follow co-founder Jonathan Kuplack in the Mammoth 200 race, covering 214 miles in the Eastern Sierra’s.
The purpose of this race is to:
1) Inspire men to break out of their comfort zone and seriously undertake their God-given mission;
2) Raise the funds to operate dynamic intensives, challenging men to step into the greatness for which they were made.

Our Four Pillars
Sebaste has built its mission on four core pillars - pillars that serve the innate, and too often unfulfilled, needs of all men.
Devotion: The truly devoted man lives a life of strong and zealous action properly ordered toward an end higher than himself.
Adventure: We live in a world tyrannized by safety. Adventure is not only the antidote, but a need hardwired into the soul of every man.
Challenge: Sebaste uses trial and physical challenge as a means to confront our own weakness, and - by accepting it - to transcend it.
Brotherhood: Sebaste uses mentorship and the fraternal experience of the poetic and the painful to form bonds that hold society together and last into eternity.
Our founders
Men brought together by the desire to help men and boys reclaim a masculine identity rooted in adventure, hardship and fraternity.

Co-Founder Jeremy Gay is a husband and father who lives in the small town of Gallup, NM. After getting married, he attended law school and practiced law as an officer for the USMC for 5 years. He and his wife and their seven children moved to Gallup because of its charm and inconvenience. Having had a love of the difficult instilled in him in each of the institutions he was a part of, he and his dear friend Johnny Kuplack embarked on the journey of creating a program that would instill in boys and men a similar love for adventure, sacrifice and brotherhood.

Johnny has dedicated the past 18 years of his life to teaching and mentoring young men around the country and has led courses from the grade school to the university levels. These mentorship efforts have recently taken shape in Sebaste, a New Mexico based nonprofit of which he is the co-founder.
Named for 40 Roman soldiers in the 3rd century who chose to meet death on a frozen lake rather than renounce Christ, Sebaste runs formative programs and adventures for men across the country.
Johnny is currently on “The Via Magna” a journey consisting of 100 ultra marathons in 100 days in a route spanning the continent of North America in order to challenge himself and all who witness him to embark on the transformative adventure of God’s love.
Virtue through trial
Sebaste helps men reclaim their masculinity through trial, training, and mentorship.
