1.  They who have been taught to believe “In One God the Father Almighty,” ought also to believe in His Only-begotten Son.  For he that denieth the Son, the same hath not the Father 1 John ii. 23..  I am the Door Ib. x. 9., saith Jesus; no one cometh unto the Father but through Me Ib. xiv. 6..  For if thou deny the Door, the knowledge concerning the Father is shut off from thee.  No man knoweth the father, save the Son, and he to whomsoever the Son shall reveal Him Matt. xi. 27..  For if thou deny Him who reveals, thou remainest in ignorance.  There is a sentence in the Gospels, saying, He that believeth not on the Son, shall not see life; but the wrath of God abideth on him. John iii. 36.  For the Father hath indignation when the Only-begotten Son is set at nought.  For it is grievous to a king that merely his soldier should be dishonoured; and when one of his nobler officers or friends is dishonoured, then his anger is greatly increased:  but if any should do despite to the king’s only-begotten son himself, who shall appease the father’s indignation on behalf of his only-begotten son?
