Reasons for being put under discipline by both the Open and Exclusive Brethren include disseminating gross Scriptural or doctrinal error or being involved in unscriptural behavior. Being accused of illegal financial dealings may also result in being put under discipline. Another less clear difference between assemblies lies in their approaches to collaborating with other Christians. Many Open Brethren will hold gospel meetings, youth events, or other activities in partnership with non-Brethren Evangelical Christian churches. More conservative Brethren tend to not support activities outside their own meetings. International Brethren Conferences on Mission (IBCM) were founded in 1993 in Singapore by unions of churches from various countries. According to an IBCM Network census released in 2020, they claimed 40,000 churches and 2,700,000 members in 155 countries. Exclusive Brethren Exclusive Brethren have remained attached to Darby's doctrine. They are more interdependent, more conservative with a propensity for a dress code, very attached to the spontaneity of worship and preaching. They form several more or less compartmentalized circles of communion, from the most moderate to the narrowest. The movement has a Protestant theology and recognizes infant baptism. Around 40,000 worldwide in 2012, "close" brothers are often referred to as Darbyists, but rarely refer to themselves as such. Plymouth Brethren Christian Church The term Exclusive Brethren is most commonly used in the media to describe one separatist group known as Taylor-Hales Brethren, who now call themselves the Plymouth Brethren Christian Church (PBCC). The majority of Christians known as Exclusive Brethren are not connected with the Taylor-Hales group, who are known for their extreme interpretation of separation from evil and their belief of what constitutes fellowship. In their view, fellowship includes dining out, business and professional partnerships, membership of clubs, etc., rather than just the act of Communion (Lord's Supper), so these activities are done only with other members. The group called the Raven Brethren (named for prominent Exclusive leader F.E. Raven) seceded from the Raven-Taylor-Hales group and are less strict and isolationist. Exclusive Brethren groups who are not affiliated with PBCC prefer being referred to as Closed rather than Exclusive brethren to avoid any connection with these more strident groups. Brethren labels and distinctions Terminology which sometimes confuses Brethren and non-Brethren alike is the distinction between the Open assemblies, usually called "Chapels", and the Closed assemblies (non-Exclusive), called "Gospel Halls." Contrary to common misconceptions, those traditionally known as the "Closed Brethren" are not a part
