The problem of many churches today is there is only worship. There is no fellowship. There is no fellowship, because there is nothing in common between day and night, light and darkness, righteousness and wickedness, believers and unbelievers. (2 Corinthians 6:14)
Though worship itself is rarely influenced, lack of fellowship ails the body unhealthily. There are darkness, wickedness, unbelievers, because though they seek the kindness of a church, they love not the word of God. The goodness they speak of, is ruled by their selfishness and pride. There is no sacrifice, there is no piety.
Then it would be the few, like the widow(Luke 21:1) or the tax collector(Luke 18:10), that come towards His holy temple, the house of prayer, with a quiet relationship with God. And the other few, whom God called to judge the world and the pharisees of today (those who twist God's words for their own selfish peace and harmony).
There can be no toleration, with those who received the Gospel and yet justify their sins. If toleration comes from ecclesiastical leadership, then history will only repeat itself.
