This is Latin, and if you ever need help in Latin I am always available to help I have taken 6 years of Latin. :)
Macula non est in te means ," There is no spot in you."
Macula means spot, non is no, est is is, in is just in, and te is you.
I am guessing this is some type of religious quote referring to something like there is not hope in thee.
Hope this helps! If you need anymore help or further explanation just let me know!! :)
