Our Identity

Founding Verse

“Behold how good and how pleasant it is for brothers to dwell together in unity!” — Psalm 133:1

Origin of the Fraternity

Beta Upsilon Chi was formed at The University of Texas at Austin in the spring of 1985 by a handful of Christian men who desired an alternative to the present fraternal lifestyle. A group of Christian men met and planned the “BYX Island Party” to formally announce the fraternity’s founding. It was the vision of the founding fathers to have a fraternity of committed Christian men, based on the unique brotherhood that a Christian atmosphere affords, for the purpose of fellowship and glorification of Jesus Christ. Through such events as parties, service projects, and evangelical outreaches, the charter members of Beta Upsilon Chi chose to unite in fellowship and glorify Jesus Christ on the University of Texas campus.

After beginning at the University of Texas, the vision of Brothers Under Christ has spread to dozens of campuses and thousands of members across the country.

Doctrinal Statement


We believe there is one God, eternally existing in three persons: the Father, the Son, and the Holy Spirit.


We believe that the Bible is God's written revelation to man, that it is uniquely inspired, and wholly authoritative.


We believe in the deity of Jesus Christ, His virgin birth, His sinless life, His miraculous works, His substitutionary death, His bodily resurrection, His ascension into heaven, His present ministry of intercession for us, and His return to earth in power and glory.


We believe in the personality and deity of the Holy Spirit, that He performs the miracle of regeneration in new believers--sealing them for the day of redemption--and then indwells them, thus enabling them to live godly lives.


We believe that man was created in the image of God, but because of sin, became alienated from God. But God, while we were still sinners, demonstrated His own love toward us by sending His only Son, Jesus Christ, to die on a cross in our place. Thus, the removal of that alienation was made possible by His grace, and indeed has been applied to everyone who has trusted in the death and resurrection of Jesus Christ alone for his salvation.
