The Summa Contra Gentiles is the second of Thomas Aquinas’s three great theological syntheses, written after his Commentary on the Sentences of Peter Lombard and before his Summa Theologiae. 
The Summa Contra Gentiles is
 commonly thought to be composed with a missionary intention, possibly 
for the use of Thomas’s brethren in their work of explaining the faith 
to non-Christians, especially Muslims in Spain. 
This volume contains the
 third and fourth books of the Summa Contra Gentiles. 
Book 
3 treats of God’s providence over all of creation from the perspective 
of what can be known on the basis of human reason. 
Book 4 treats of 
matters of faith surpassing human reason: the Trinity of Persons in God,
 the Incarnation of the Divine Word, the Work of Salvation, and the Last
 Things.
