In Nomine Patris, et Filii, et Spiritus Sancti. Amen.
Upon the True Faith of a Christian, may God witness that I hereby vow and dedicate myself as a servant of Christ and the poor, the first qualification of a true Knight.
I promise to be faithful and loyal to Christ and to be guided by the ideals of the Sovereign Hospitaller Order of St. John of Jerusalem: to contribute to its glory, protection, prosperity, support and utility.
To combat everything prejudicial to its well-being; never to act contrary to its dignity, but to conduct myself always as a true Knight of Christ: a good Christian and a person of honour. Believing that Christ will grant me a special token of His favour, I therefore, in all humility, charity, and respect agree to join with every sincere and Godly Christian of whatever church, to bring about by prayer and deed the salvation of the Christian world by helping to promote a lasting Christian unity.
I will adorn my Knighthood with true charity, the mother and solid foundation of all virtues.
I will wear on my person the Christian Maltese Cross of eight points, to constantly remind me of my religious vow of always bearing in my heart the Cross of Jesus Christ, adorned with the virtues that attend it.
So help me God.
