It is illegal to leave the Islamic faith, and new believers will face intense opposition from their families and communities. Disgracing the family in this way is considered the worst thing a person can do. They can be pressured, disowned, locked away, beaten, or even killed. 

Therefore, most Saudi Christians tend to follow their faith quietly. This can extend to not even telling their spouse or children about their faith, for fear that extended family members or school staff could discover they have left Islam. There are no legal church buildings or meetings. But secret believers have become bolder in recent times, sharing their faith with others through technology. But those caught doing this have faced serious repercussions.  

Most Christians living in Saudi Arabia are temporary workers from other countries. They are forbidden from sharing their faith with local Saudis, and gathering for worship is restricted. Breaking these rules can get them detained and deported.
