You, Kamal, have been called by Almighty God in his fatherly love to the ministry of the Word and Sacraments and ordained by the Church and have now been appointed to the Pastoral Charge of St Mary's, I charge you anew in the name of the Lord Jesus Christ to walk worthy of the vocation to which you are called, with all humility, with long suffering, forbearance and peaceful behaviour, for the perfecting of the saints, for the work of the ministry, for the upbuilding of the body of Christ.Take heed to yourself and to the flock over which the Holy Spirit has made you overseer. Love Christ and feed his flock, taking the oversight of it, not as one who lords it over the people committed to you but being an example to all in word, in conduct, in love, in spirit, in faith, and in purity.Give attention to reading, to exhortation and to teaching. Do the work of an evangelist. Do not neglect the gift which is in you. Endure hardship as a good soldier of Jesus Christ. Pray always, watching with all perseverance. Thus shall you save both yourself and those who hear you; and in that day when the Chief Shepherd shall appear you shall receive a crown of glory which will never fade away.Now the God of peace, that brought again from the dead our Lord Jesus, that Good Shepherd of the sheep, make you perfect in every good work to do his will working in you that which is well pleasing in his sight, through Jesus Christ; to whom be glory for ever and ever. Amen.
