This study was originally a part of a letter written to an “ecumenically-sensitive” Catholic who was part of a group that abandoned certain Catholic distinctives (such as crossing themselves, displaying the crucifix, venerating the Blessed Virgin, etc.) in an effort to “not offend the Protestant brethren”.
