While this is a prayer for vocations in general, fraternity members recite it at each meeting for the vocation of the seminarian we support. It was obtained from dcpriest.org.
Almighty and merciful Father, you inspire and bring to fulfillment every good intention. Guide your people in the way of salvation and watch over those who shepherd your flock and those who have left all things to follow you. Raise up worthy ministers for your altars, ardent but gentle servants of the Gospel, and generous souls who renounce worldly power and profit to serve you and their brothers and sisters faithfully in the spirit of poverty and humility. Inspire our young men and women to respond to your call so that your Church might always rejoice in plentiful servants for your harvest. We ask this through Jesus Christ, your Son, our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
