text_A: In the Eastern Orthodox Christian tradition there are reports of particular, wonderworking icons that exude myrrh (fragrant, healing oil), or perform miracles upon petition by believers. When such reports are verified by the Orthodox hierarchy, they are understood as miracles performed by God through the prayers of the saint, rather than being magical properties of the painted wood itself. Theologically, all icons are considered to be sacred, and are miraculous by nature, being a means of spiritual communion between the heavenly and earthly realms. However, outside of the Eastern Orthodox church, it is extremely rare for specific icons themselves to be characterised as "miracle-working", meaning that God has chosen to glorify them by working miracles through them. Such icons are often given particular names (especially those of the Virgin Mary), and even taken from city to city where believers gather to venerate them and pray before them. Islands like that of Tinos are renowned for possessing such "miraculous" icons, and are visited every year by thousands of pilgrims.
text_B: Is it likely that there would be so few icons that were considered to be miracle-workers in their own right, that any individual icon could be given a very broad name without having to further specify its location or the time the miracle was thought to have occurred?
YES.
