344、信有何用，即关于信的记忆知识、认知和教义有何用？不就是让人可以变成信所教导的样子吗？信所教导的第一件事就是仁（马可福音12:28-34；马太福音22:35-40），仁是信所关注的一切事物的目的。如果人不变成知识或教义所教导的样子，那么一切知识或教义不就形同虚设了吗？

[NCE]344. What purpose is there to faith, or to the facts, insights, and teachings of faith, except that we may become what faith teaches us to be? And the primary thing it teaches is charity, as stated in Mark 12:28-34 and Matthew 22:35-40. That is the goal toward which faith looks in all it does. If we do not gain charity, what is knowledge, or doctrine, but a nothing?{*1}
Footnotes:
{*1} This is an echo of 1 Corinthians 13:2: "Though I have the gift of making prophecies, though I understand all mysteries and all knowledge, and though I have all faith, faith to move mountains, if I do not have charity, I am nothing." [RS]

344. What avails faith, that is, the memory-knowledge [scientia], the knowledge [cognitio], and the doctrine of faith, but that the man may become such as faith teaches? And the primary thing that it teaches is charity (Mark 12:28-35; Matt. 22:34-39). This is the end of all it has in view, and if this be not attained, what is all knowledge or doctrine but a mere empty nothing?
344. What is the use of faith, that is, what is the use of knowledge, awareness, and doctrine related to faith, other than of becoming such as it teaches? The first thing faith teaches is charity, Mark 12:28-35; Matt 22:35-40, charity being the end of everything faith has in view. If a person does not become as it teaches, what is knowledge or doctrine but something which is in fact nothing?
Latin(1748-1756) 344
344. Quid facit fides, seu scientia, cognitio, et doctrina fidei, quam ut homo ita fiat sicut docet? Primarium quod docet, est charitas, Marc. xii 28-35; Matth. xxii 34-39; haec est finis omnium, quo spectat; si non fiat, quid scientia seu doctrina, nisi quoddam nihil?
