In contrast to the Roman Catholic Church, where interpretation of scripture is carried out by the Pope and his Bishops, Protestantism encourages 'Private Interpretation' of scripture by the individual. As a direct result, differing denominational groups have emerged, each holding to distinctive doctrines. Each regards itself as part of the 'Invisible Church' i.e. the union of believers on earth and in heaven, known only to God.
There are also growing numbers of non-denominational churches. This term, while implying non-alignment with a specific (Protestant) denomination is also usually understood to mean a church in agreement with the Five Soli of Protestantism. An example are the Vineyard group of Churches.
