The Orange Institution is a Christian organization.

As Orangemen our trust is in God and our faith and dependence is in Jesus Christ, the Saviour and Lord of mankind. Our purpose is to maintain the Christian faith by word and deed; to propagate and defend that faith which we have received from the Church of the New Testament through the faithfulness of the Protestant Reformers. It is Christ-centred, Bible-based, Church-grounded. By it we are moulded in character and conduct.
The Orange Institution is set for the defence of Protestantism. This is true to the intention of Orangemen who are committed to the Christian faith with its Reformation emphasis on a personal relationship with Jesus Christ as the Lord and Saviour of mankind. There are also the Protestant beliefs in freedom of conscience; the priesthood of all believers and the primary place and purpose of the Holy Bible in Christian faith and conduct.
We proclaim "Civil and religious liberty for all, special privileges for none". We do not deny to others their civil and religious liberties; we expect the same tolerance from them. We shall be strong for truth, for peace, for the making of a good, fair and just society to which we shall contribute liberally as good citizens.
