In these "latter days," there are few people who haven’t been visited at least once by Mormon missionaries. At some point in your doorstep dialogue, these earnest young men will ask you to accept a copy of the Book of Mormon, read it, and pray about it, asking the Lord to "send the Holy Ghost to witness that it is true." Then, very solemnly, they’ll "testify" to you that they know theBook of Mormon is true, that it’s God’s inspired word, and that it contains the "fullness of the everlasting gospel."
~ Maximus, martyr, saint, about A.D. 250, in answer to the demand of the civil authorities for sacrifice to the pagan gods; a test in common use as belief in a single Godhead was known to be definitive in the early Christian community; thus any Christian might be called on to seal with his blood his faith in the One God. (See: The Blessed Trinity)
