I remember learning a while ago that we are supposed to burn missionary material, presumably because it is kefirah. At one point a local missionary was specifically targeting us and putting it through our letterbox regularly and it was getting quite annoying to keep getting the incinerator bin and blowtorch out (especially if it was raining, and I'm sure the paper was designed to be hard to burn!).
- Is the mitzva to burn it immediately or is it allowable to wait until it is convenient?
- Are alternative methods of disposal acceptable?
