In the Confessions and the Letters, moreover, the Manich#65533;ans figure prominently. The treatises included in the present series may be said to fairly represent Augustin's manner of dealing with Manich#65533;ism. The Anti-Manich#65533;an writings are found chiefly in vol. VIII. of the Benedictine edition, and in volumes I. and XI. of the Migne reprint. Augustin's personal connection with the sect extending over a period of nine years, and his consummate ability in dealing with this form of error, together with the fact that he quotes largely from Manich#65533;an literature, render his works the highest authority for Manich#65533;ism as it existed in the West at the close of the fifth century.] Comp. also the Acts of Councils against the Manich#65533;ans from the fourth century onwards, in Mansi and Hefele [and Hardouin].
