Some clerics and laity may be against it. The need for conversion still stands.
The ancient liturgical churches have become purely ethnic organizations that rely on sexual reproduction to keep going. Instead of engaging in missionary activity they publish and propagate the notion that it is something to be defended against. Is it any wonder so many Protestants think that liturgical chr*stians (and Jews, for that matter) don't have a leg to stand on? They act as if to hear the Protestant message would automatically lead to conversion to Protestantism. Are the ancient religions that unsure of their message?
