O zealous apostle who traveled throughout the earth driven by the fire of the Holy Spirit, you labored strenuously, rejoicing in poverty and welcoming hardships as you gave your very life for the flock in your care – pray the love of Christ will urge us on to holy zeal that we might approach your apostolic spirit, desiring to inflame all men with the fire of God’s love. Concerned always and only for the glory of God and the salvation of souls, may we fulfill our call; as sons of the Immaculate Heart of Mary, with her same purity and commitment, pray we give birth to Christ in souls by the preaching of the Gospel until all are formed in His image in the heavenly kingdom.
