The Trinity, Islam and the Scriptures

Article 9 of the Belgic Confession looks at the Biblical backing for the doctrine of the Trinity. Why are Protestants often so weak with regard to the Trinity? I give four reasons. We also look at how Islam was designed to oppose Christianity's most fundamental article of faith from the days of Abd al-Malik, and the building of the Dome of the Rock. Lastly we look at the Holy Scripture's rich testimony to a Triune God.
