Are you familiar with the "Emmaus Road Retreats"? Is this something for a believer to go to?
This retreat is sponsored by the Roman Catholic Church, which is a false religion, for they have a false gospel of salvation (Jesus + your works = salvation). They are a religion with truth and error mixed together and as such we need to stay far away from their ministries.
2 Corinthians 6:14-17
 Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?  What harmony is there between Christ and Belial*? What does a believer have in common with an unbeliever?  What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: "I will live with them and walk among them, and I will be their God, and they will be my people."  "Therefore come out from them and be separate."
