costestes e spiritu silentio
costestes is not a classical latin word but might be medieval or church latin. cotestes could be a word (not classical) meaning something like co-witnesses. e spiritu (if they are the proper words) could mean out of/derived from the spirit (holy?). silentio is the dative or ablative singular of the neuter noun silentium meaning silence and could mean to/for/by/with/from/in/at/on (the) silence. but unless an accurate copy of the words can be obtained, i fear there is little chance of solving the riddle.
