503、上古教会的感知力不仅在于感知何为良善和真理，还在于行善的欢喜和快乐。没有行善的这种欢喜快乐，感知力就没有生命，欢喜快乐是感知力的生命的源头。诸如上古教会所享有的那种爱和源于爱的信之生命，是发挥功用的生命，也就是伴随功用的良善与真理的生命。主从功用，通过功用并照着功用赋予生命。没有用的东西不可能有生命在里面，因为凡没有用的东西，都被丢弃。在这方面，上古之人是主的样式，因而在感知力上也成为祂的形像。感知力在于知道何为良善与真理，因而知道何为信的实质。人若拥有爱在里面，就不会满足于知道，还要以行良善和真理，也就是致力于功用为快乐。

[NCE]503. The earliest church's perceptive ability was not restricted to an awareness of what was good and true but included happiness and joy in doing good. Without happiness and joy in doing good, perception is not alive; from that happiness and joy it lives. The living quality of love and of the faith that comes from love, such as it was in the earliest church, is a quality we have when we are being useful, or when we adopt the goodness and truth that come from useful activity. Usefulness is the source from which, the means by which, and the measure according to which the Lord gives us life. Nothing useless can have any life in it, because anything that is useless is rejected.
In this, the earliest people were likenesses of the Lord; consequently in their perceptive abilities they became images of him. To be perceptive is to recognize what is good and true and so what is appropriate to faith. One who is under the influence of love is not satisfied with just knowing what is good and true but wants to do it — that is, to be useful.
Potts(1905-1910) 503
503. The perceptive faculty of the Most Ancient Church consisted not only in the perception of what is good and true, but also in the happiness and delight arising from well-doing; without such happiness and delight in doing what is good the perceptive faculty has no life, but by virtue of such happiness and delight it receives life. The life of love, and of the derivative faith, such as the Most Ancient Church enjoyed, is life while in the performance of use, that is, in the good and truth of use: from use, by use, and according to use, is life given by the Lord; there can be no life in what is useless, for whatever is useless is cast away. In this respect the most ancient people were likenesses of the Lord, and therefore in perceptive powers they became images of Him. The perceptive power consists in knowing what is good and true, consequently what is of faith: he who is in love is not delighted in knowing, but in doing what is good and true, that is, in being useful.
Elliott(1983-1999) 503
503. The perceptivity of the Most Ancient Church lay not merely in their perceiving what good and truth were but also in the joy and delight of doing what was good. Without this joy and delight of doing what is good perceptivity is without life. They are the source of its life. The life of love and faith deriving from it, such as the Most Ancient Church possessed, is a life that comes with performing use, that is, with the good and truth that accompany use. It is from use, by way of use, and according to use,that life is imparted by the Lord. And that which is without use can have no life in it, for that which is without use is casta side. In this respect those people were likenesses of the Lord, and in their perceptivity therefore became images too. Perceptivity is knowing what good and truth are, and so knowing what is the substance of faith. Anyone who has love within him is not content just with knowing, but with doing what is good and true, that is, with engaging in a use.
Latin(1748-1756) 503
503. Perceptivum Ecclesiae Antiquissimae non solum constabat in eo quod perceperint quid bonum et verum, sed in felici et jucundo bonum agendi; absque felici et jucundo bonum agendi, perceptivum non est vivum, sed inde vivit; vita amoris et inde fidei qualis fuit Antiquissimae Ecclesiae, est vita dum in usu seu in bono et vero usus; ex usu, per usum et secundum usum datur vita a Domino; inutili nulla potest esse vita, nam quicquid inutile est, rejicitur: in illo fuerunt similitudines Domini; quare etiam in perceptivis facti sunt imagines; perceptivum est nosse quid bonum et verum, ita quid fidei; qui in amore est, is non delectatur nosse, sed facere bonum et verum, hoc est, usui esse.
