This Divine Word, then, was united with his creature(208), (which union is expressed by the name _Emmanuel_(209),) and humbled himself to take upon him the infant state of man(210), and thus having become Son of man(211), went through all the ages of man(212), and finally hung upon the cross(213). He asserts, moreover, that although the angels knew the Father solely by the revelation of the Son(214), and indeed all from the beginning have known God by the Son(215), so that the Father is the Son invisible, and the Son the Father visible(216), yet that the Son knew not the day of judgment(217); and that this was so ordered, that we may learn that the Father is above all(218), and that the Son ministers to the Father(219): finally, that when Jesus was tempted and suffered, the Word in him restrained his energy(220). But he declares likewise that Christ remained in the bosom of the Father, even when upon earth(221). These mysteries in the nature of Christ Irenæus does not attempt to explain, fully holding the eternal and unchangeable Divinity of the Son, even when made flesh, and his strict personal union with that flesh, and at the same time asserting his subordination to the Father, even in his divine nature; feeling that when we cannot discover the reason of every thing, we should consider the immeasureable difference between us and God(222); that if we cannot explain earthly things, we cannot expect to explain heavenly things, and that what we cannot explain we must leave to God(223); and in short that it is much better to know nothing but Christ crucified, than by subtil inquiries to fall into impiety(224). This Jesus, then, who has been testified of by all things that he was truly God and truly man(225), being related to both God and man, and thus having the indispensable qualification for his office, became the Mediator between them(226); he came in every dispensation, and summed up all things in himself(227). He was born about the forty‐first year of the reign of Augustus(228); when not full thirty he was baptized, but he did not begin to teach till past forty(229). His ministry extended through three passovers(230), and he suffered on the day of the passover(231). He is our High Priest(232); he gave his soul for our souls, and his flesh for ours (233); his righteous flesh has reconciled to God our sinful flesh (234); and he brings us into union and communion with God(235). He rose again in the flesh(236), and in the flesh he ascended into heaven, and will come again to judgment(237); and he introduces his Church into the kingdom of heaven(238).
