For full reports and exact statements of the CRCNA position on a particular issue, see references provided below.
There is an irreconcilable conflict between the teachings and practices of the lodge and those of biblical Christianity; therefore simultaneous membership in the lodge and in the church of Jesus Christ is incompatible with and contrary to Scripture.
From its beginning the CRC has held a strong position against lodge membership. In fact, it was one of the issues that caused the CRC to separate from the Dutch Reformed Church. In 1900 a report on lodge membership was adopted; another was adopted in 1977.
