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 the holy commandments; through the same Jesus Christ our Lord. Amen.
IF thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness, and with the mouth confession is made unto salvation. For the Scripture saith, Whosoever believeth on him shall not be ashamed. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved. How then shall they call on him, in whom they have not believed? And how shall they believe in him, of whom they have not heard? And how shall they hear without a preacher? And how shall they preach, except they be sent? As it is written, How beautiful are the feet of them that preach the Gospel of peace, and bring glad tidings of good things! But they have not all obeyed the Gospel. For Esaias saith, Lord, who hath believed our report? So then faith cometh by hearing, and hearing by the word of God. But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world. But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you. But Esaias is very bold, and saith, I was found of them that sought me not; I was made manifest unto them that asked not after me. But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people.
St. Matthew 4:18-20
JESUS, walking by the sea of Galilee, saw two brethren, Simon called Peter, and Andrew his brother, casting a net into the sea, (for they were fishers;) and he saith unto them, Follow me; and I will make you fishers of men. And they straightway left their nets, and followed him. And going on from thence he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and he called them. And they immediately left the ship and their father, and followed him.
