The Church also refers to an institution of worship. Generally but not necessarily, the institution is a Christian one. Many subtypes exist, foremost of these being the Roman catholic Church and the Anglican Church. Other sects of varying sizes exist such as the church of the latterday saints, and the protestant church. Kudos to Landover Baptist Church - they have my soul.

The different sects are idealistically due to differences in opinion, however often the motives behind their formation were political instead of ideological - for instance the Anglican religion - see Henry VIII. Historically, much blood has been shed based on religious wars.
