Now faith is the assurance of things hoped for, the conviction of things not seen. (Hebrews 11.1)
“Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and the house of Judah, 32 not like the covenant which I made with their fathers when I took them by the hand to bring them out of the land of Egypt, my covenant which they broke, though I was their husband, says the Lord. 33 But this is the covenant which I will make with the house of Israel after those days, says the Lord: I will put my law within them, and I will write it upon their hearts; and I will be their God, and they shall be my people. 34 And no longer shall each man teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, says the Lord; for I will forgive their iniquity, and I will remember their sin no more.” (Jeremiah 31.31-34)
“If you love me, you will keep my commandments. 16 And I will pray the Father, and he will give you another Counselor, to be with you for ever, 17 even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him; you know him, for he dwells with you, and will be in you. 18 “I will not leave you desolate; I will come to you. 19 Yet a little while, and the world will see me no more, but you will see me; because I live, you will live also. 20 In that day you will know that I am in my Father, and you in me, and I in you. 21 He who has my commandments and keeps them, he it is who loves me; and he who loves me will be loved by my Father, and I will love him and manifest myself to him.” 22 Judas (not Iscariot) said to him, “Lord, how is it that you will manifest yourself to us, and not to the world?” 23 Jesus answered him, “If a man loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him. 24 He who does not love me does not keep my words; and the word which you hear is not mine but the Father’s who sent me. 25 “These things I have spoken to you, while I am still with you. 26 But the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and bring to your remembrance all that I have said to you. (John 14.15-26)
- But in learning the Faith and in professing it, acquire and keep that only, which is now delivered to thee by the Church, and which has been built up strongly out of all the Scriptures. For since all cannot read the Scriptures, some being hindered as to the knowledge of them by want of learning, and others by a want of leisure, in order that the soul may not perish from ignorance, we comprise the whole doctrine of the Faith in a few lines. This summary I wish you both to commit to memory when I recite it, and to rehearse it with all diligence among yourselves, not writing it out on paper, but engraving it by the memory upon your heart, taking care while you rehearse it that no Catechumen chance to overhear the things which have been delivered to you. I wish you also to keep this as a provision through the whole course of your life, and beside this to receive no other, neither if we ourselves should change and contradict our present teaching, nor if an adverse angel, transformed into an angel of light should wish to lead you astray. For though we or an angel from heaven preach to you any other gospel than that ye have received, let him be to you anathema. So for the present listen while I simply say the Creed, and commit it to memory; but at the proper season expect the confirmation out of Holy Scripture of each part of the contents. For the articles of the Faith were not composed as seemed good to men; but the most important points collected out of all the Scripture make up one complete teaching of the Faith. And just as the mustard seed in one small grain contains many branches, so also this Faith has embraced in few words all the knowledge of godliness in the Old and New Testaments. Take heed then, brethren, and hold fast the traditions which ye now receive, and write them an the table of your heart.
- Guard them with reverence, lest per chance the enemy despoil any who have grown slack; or lest some heretic pervert any of the truths delivered to you. For faith is like putting money into the bank, even as we have now done; but from you God requires the accounts of the deposit. I charge you, as the Apostle saith, before God, who quickeneth all things, and Christ Jesus, who before Pontius Pilate witnessed the good confession, that ye keep this faith which is committed to you, without spot, until the appearing of our Lord Jesus Christ. A treasure of life has now been committed to thee, and the Master demandeth the deposit at His appearing, which in His own times He shall shew, Who is the blessed and only Potentate, the King of kings, and Lord of lords; Who only hath immortality, dwelling in light which no man can approach unto; Whom no man hath seen nor can see. To Whom be glory, honour, and power for ever and ever. Amen. (St. Cyril of Jerusalem, Catechetical Lectures, Number 5)
