Is there Christian scripture or literature absolving the old Jewish laws of usury? Most people are aware that Jewish law forbade earning interest from the lending of money to another. As Christianity gained momentum in the early first and second century, many of the Mosaic laws were abandoned, although certain aspects remained in place - for example, punishments for parental disrespect were abandoned although Christians taught that a child ought to respect his or her parents. 

Is this another case of the letter of the law morphing into the spirit of the law? Christians seem to generally believe that it's sinful to impoverish another by means of lending practices, but that doesn't really stop many forms of interest charging that were previously forbidden. Is there any relevant scripture or literature relating to usury after the death of Christ?

The New Testament contains references to usury, notably in the Parable of the talents:

Well then, you should have put my money on deposit with the bankers, so that when I returned I would have received it back with interest.
—Matthew 25:27

So interest was accepted, otherwise Jesus wouldn't have used that as an example?

&quot;Give to the one who asks you, and do not turn away from the one who wants to borrow from you.&quot;
—Matthew 5:42
&quot;And if you lend to those from whom you expect repayment, what credit is that to you? Even sinners lend to sinners, expecting to be repaid in full. But love your enemies, do good to them, and lend to them without expecting to get anything back. Then your reward will be great, and you will be children of the Most High, because he is kind to the ungrateful and wicked.&quot;
—Luke 6:34-35

This suggests that you shouldn't even accept repayment, never mind interest.

&quot;Give, and it will be given to you. A good measure, pressed down, shaken together and running over, will be poured into your lap. For with the measure you use, it will be measured to you.”
—Luke 6:38

So there is nothing absolving the rules, and abolishing them, but there is equally nothing that reiterates that they are wrong - to the contrary, there is a parable that speaks about it in a good light.
