World Day of Prayer For Vocations This Sunday is the World Day of Prayer for Vocations. In 1963 Pope Paul VI designated Good Shepherd Sunday as World Day of Prayer for Vocations. Christ Jesus, the Good Shepherd, knows us well and gives his life for us. In the name of Christ Jesus we rejoice in the Good Shepherd who leads us into fullness of life. As we celebrate this feast we pray for fidelity to our vocation.
