Needed Truth Brethren, as they are sometimes known, call themselves, “The Churches of God in the Fellowship of the Son of God, the Lord Jesus Christ". They began as a split from the Open Brethren around 1892 (known as "The Separation". Only a few assemblies of the Open Brethren officially separated and joined the group. However, it seems likely that their teaching thoroughly infiltrated into what is sometimes known as the "Tight Brethren", or "Closed-Opens", or "Gospel Hall Brethren".
