I might want my children to marry within the faith but in the end, it’s one big family not always happy but family all the same. The 3 major religions all have the same roots and have more in common “especially today” than what pulls them apart. Even within the individual faiths, those who truly wear the cloth have fewer similarities than those that wear shorts. Those that actually practice Christianity, Islam & Judaism therefore can tie a knot even if it’s from a whole new pair of sneakers.
