personally I support any church that practices and preaches that Jesus Christ is God and the way to heaven.
The exact denomination is the least of the concerns. The biggest concern is that the church follows the Bible, lives out the faith, and has a passion and a mission. You will know when you visit a church that is focused on the mission of Christ.
I have not specifically studied the theology of the CRC, but if they or any other church are crazy liberal and bend the scriptures to fit their needs, run.
