28 Take heed therefore unto yourselves, and to all the flock, whereof the holy Ghost hath made you Overseers to feed the Church of God which he hath purchased with that his own blood.
29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. 30 Moreover of your own selves shall men arise speaking perverse things, to draw disciples after them. 31 Therefore watch, and remember, that by the space of three years I ceased not to warn everyone, both night and day with tears. Acts 20:28-31 (1599 Geneva Bible)
True Christianity is exclusive. It is not a smorgasbord or buffet of options from which men may take what they like while rejecting the rest and still call themselves Christians. While a statement like that may not be popular in this post-modern 21st Century culture which advocates tolerance that is sort of a give and take “conversation” in which people with opposing views find a middle ground, it is still the truth.
