ROME – As the abuse case of famed Slovene priest and artist Father Marko Ivan Rupnik continues to perplex Catholics around the globe, experts have warned that a perceived gap in church law regarding an offense known as “false mysticism” is preventing him and other alleged abusers from facing prosecution.

However, some observers believe that a recent case out of Spain could set a precedent needed for these cases to be more swiftly and thoroughly handled in the future.

Contemporary Catholicism’s most famed muralist, Rupnik, 68, is accused of engaging in sexual, psychological and spiritual abuse of at least 25 adult women over a 30-year period. For over a year now, the case has plagued the Church in large part due to several question marks over how it’s been handled, including the response of Pope Francis himself.
