Oliver of Paderborn proved the Trinity from the Qur’anic breath of God

Evidence

As God is simple in nature and there is nothing in God which is not God, and (Christ) was conceived by the breath of God, it is evident that He is God; and the breath of God is nothing but the Holy Ghost, and the speech of God nothing else but the Word of God. — Norman Daniel, Islam and the West, 998

Categorization

• DEFINE: Illustrates the ‘false-Augustinian temper’ — reasoning from shared premises of the rival scripture toward Christian conclusions.
• CANDY: The neat syllogism that ‘God’s breath = Holy Ghost, God’s speech = Word’ is a neat, quoteable bit of medieval logical ingenuity.
