If the church of Satan opened a sacrificial temple on the corner of your block with a large pitchfork instead of a steeple, your religious  neighbors would be outraged.  But not outraged enough.  The "Christian community" would likely cower in shame while the political correctness mavens advocate in support.   Many of your neighbors would visit the dark rituals out of curiosity and some would join to be "cool."
 
Of course Satan is usually not quite that blatant.  He's becoming bolder all the time but for now he prefers a more subtle approach.   Satan is a master counterfeiter:   "For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.   And no marvel; for Satan himself is transformed into an angel of light.   Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works." (2 Corinthians 11:13-15)    The most dangerous of Satan's lies is religion.  Religion pulls you away from the simple grace of God and puts you on a performance based treadmill.

The most blatant of religions that call themselves "Christian" is the Catholic Church.   Pope Paul VI, November 21, 1962 (Vatican II) said that the Catholic church is the only way to salvation.  He said that baptism is the "door" into the church (the Catholic church exclusively).  He said that a person could not be saved apart from the Catholic church.  However,   John 10:9 makes it clear that Jesus is the only door into heaven.  Acts 4:12  proclaims that that salvation is exclusively through Jesus Christ.  There is no other way.  Ephesians 2:8-10  spells out the futility of works and explains that the grace of god is received only through the faith that God gifts you with.

Almost all organized churches and denominations have bought into the performance based religion lie.  Ask yourself the following question:  What am I doing to earn God's mercy, or Pastor Biff's approval?   God's mercy and grace is not for sale and Pastor Biffs approval will not help you connect with God. 

Jesus came to set us free.
Freedom from sin,
Freedom from religion,
Freedom from guilt:
Freedom, Free Indeed.
