IsOkToDisplayScriptureIfPresent is hardcoded to always returns true. The purpose of this property is to make it easier to disable Scripture from appearing anywhere in FieldWorks if we wanted to be able to do that at some point in the future. In any case, this property is FieldWorks-specific, which is why we removed its use from within FDO. FLEx or TE can filter out Scripture from the InterlinearTexts property if it wants to using the IsOkToDisplayScriptureIfPresent property. At this point, I can't find any FieldWorks code that actually uses this property.
