Almighty God, who didst give such grace unto thy holy Apostle Saint Andrew, that he readily obeyed the calling of thy Son Jesus Christ, and followed him without delay; Grant unto us all, that we, being called by thy holy Word, may forthwith give up ourselves obediently to fulfil thy holy commandments; through Jesus Christ our Lord. Amen.

The Epistle: Romans 10:9-21
