Religion, Science, & Unfalsifiability

Recently an interlocutor of mine claimed that religious beliefs, unlike scientific beliefs, are unfalsifiable. But beliefs of these two sorts don’t differ in this way. There is evidence for and evidence against both types of beliefs. So both kinds are at least theoretically verifiable and falsifiable. Moreover, when believers persist in maintaining beliefs in either category in the face of counterevidence, they often do so because they have adequate grounds for those beliefs and insufficient reason to think the contrary evidence is decisive. In these cases, though the beliefs are practically unfalsified, it doesn’t follow that they are theoretically unfalsifiable.
