3. Now it ought to be known that the holy apostles, in preaching the faith of Christ, delivered themselves with the utmost clearness on certain points which they believed to be necessary to every one, even to those who seemed somewhat dull in the investigation of divine knowledge; leaving, however, the grounds of their statements to be examined into by those who should deserve the excellent gifts of the Spirit, and who, especially by means of the Holy Spirit Himself, should obtain the gift of language, of wisdom, and of knowledge: while on other subjects they merely stated the fact that things were so, keeping silence as to the manner or origin of their existence; clearly in order that the more zealous of their successors, who should be lovers of wisdom, might have a subject of exercise on which to display the fruit of their talents,—those persons, I mean, who should prepare themselves to be fit and worthy receivers of wisdom.
4. The particular points[[8]] clearly delivered in the teaching of the apostles are as follow:
First, That there is one God, who created and arranged all things, and who, when nothing existed, called all things into being—God from the first creation and foundation of the world—the God of all just men, of Adam, Abel, Seth, Enos, Enoch, Noe, Sem, Abraham, Isaac, Jacob, the twelve patriarchs, Moses, and the prophets; and that this God in the last days, as He had announced beforehand by His prophets, sent our Lord Jesus Christ to call in the first place Israel to Himself, and in the second place the Gentiles, after the unfaithfulness of the people of Israel. This just and good God, the Father of our Lord Jesus Christ, Himself gave the law, and the prophets, and the gospels, being also the God of the apostles and of the Old and New Testaments.
Secondly, That Jesus Christ Himself, who came [into the world], was born of the Father before all creatures; that, after He had been the servant of the Father in the creation of all things—“For by Him were all things made”[[9]]—He in the last times, divesting Himself [of His glory], became a man, and was incarnate although God, and while made a man remained the God which He was; that He assumed a body like to our own, differing in this respect only, that it was born of a virgin and of the Holy Spirit: that this Jesus Christ was truly born, and did truly suffer, and did not endure this death common [to man] in appearance only, but did truly die; that He did truly rise from the dead; and that after His resurrection He conversed with His disciples, and was taken up [into heaven].
Then, thirdly, the apostles related that the Holy Spirit was associated in honour and dignity with the Father and the Son. But in His case it is not clearly distinguished whether He is to be regarded as born or innate,[[10]] or also as a Son of God or not: for these are points which have to be inquired into out of sacred Scripture according to the best of our ability, and which demand careful investigation. And that this Spirit inspired each one of the saints, whether prophets or apostles; and that there was not one Spirit in the men of the old dispensation, and another in those who were inspired at the advent of Christ, is most clearly taught throughout the churches.
5. After these points, also, the apostolic teaching is that the soul, having a substance[[11]] and life of its own, shall, after its departure from the world, be rewarded according to its deserts, being destined to obtain either an inheritance of eternal life and blessedness, if its actions shall have procured this for it, or to be delivered up to eternal fire and punishments, if the guilt of its crimes shall have brought it down to this: and also, that there is to be a time of resurrection from the dead, when this body, which now “is sown in corruption, shall rise in incorruption,” and that which “is sown in dishonour will rise in glory.”[[12]] This also is clearly defined in the teaching of the church, that every rational soul is possessed of free-will and volition; that it has a struggle to maintain with the devil and his angels, and opposing influences,[[13]] because they strive to burden it with sins; but if we live rightly and wisely, we should endeavour to shake ourselves free of a burden of that kind. From which it follows, also, that we understand ourselves not to be subject to necessity, so as to be compelled by all means, even against our will, to do either good or evil. For if we are our own masters, some influences perhaps may impel us to sin, and others help us to salvation; we are not forced, however, by any necessity either to act rightly or wrongly, which those persons think is the case who say that the courses and movements of the stars are the cause of human actions, not only of those which take place beyond the influence of the freedom of the will, but also of those which are placed within our own power. But with respect to the soul, whether it is derived from the seed by a process of traducianism, so that the reason or substance of it may be considered as placed in the seminal particles of the body themselves, or whether it has any other beginning; and this beginning itself, whether it be by birth or not, or whether bestowed upon the body from without or no, is not distinguished with sufficient clearness in the teaching of the church.
6. Regarding the devil and his angels, and the opposing influences, the teaching of the church has laid down that these beings exist indeed; but what they are, or how they exist, it has not explained with sufficient clearness. This opinion, however, is held by most, that the devil was an angel, and that, having become an apostate, he induced as many of the angels as possible to fall away with himself, and these up to the present time are called his angels.
7. This also is a part of the church’s teaching, that the world was made and took its beginning at a certain time, and is to be destroyed on account of its wickedness. But what existed before this world, or what will exist after it, has not become certainly known to the many, for there is no clear statement regarding it in the teaching of the church.
8. Then, finally, that the Scriptures were written by the Spirit of God, and have a meaning, not such only as is apparent at first sight, but also another, which escapes the notice of most. For those [words] which are written are the forms of certain mysteries,[[14]] and the images of divine things. Respecting which there is one opinion throughout the whole church, that the whole law is indeed spiritual; but that the spiritual meaning which the law conveys is not known to all, but to those only on whom the grace of the Holy Spirit is bestowed in the word of wisdom and knowledge.
The term ἀσώματον, i.e. incorporeal, is disused and unknown, not only in many other writings, but also in our own Scriptures. And if any one should quote it to us out of the little treatise entitled The Doctrine of Peter,[[15]] in which the Saviour seems to say to His disciples, “I am not an incorporeal demon,”[[16]] I have to reply, in the first place, that that work is not included among ecclesiastical books; for we can show that it was not composed either by Peter or by any other person inspired by the Spirit of God. But even if the point were to be conceded, the word ἀσώματον there does not convey the same meaning as is intended by Greek and Gentile authors when incorporeal nature is discussed by philosophers. For in the little treatise referred to he used the phrase “incorporeal demon” to denote that that form or outline of demoniacal body, whatever it is, does not resemble this gross and visible body of ours; but, agreeably to the intention of the author of the treatise, it must be understood to mean that He had not such a body as demons have, which is naturally fine,[[17]] and thin as if formed of air (and for this reason is either considered or called by many incorporeal), but that He had a solid and palpable body. Now, according to human custom, everything which is not of that nature is called by the simple or ignorant incorporeal; as if one were to say that the air which we breathe was incorporeal, because it is not a body of such a nature as can be grasped and held, or can offer resistance to pressure.
