The Trinity HC LD 8

How are these articles divided?
Into three parts: the first is of God the Father and our creation; the second, of God the Son and our redemption; the third, of God the Holy Ghost and our sanctification.

Since there is but one Divine Being, why do you speak of three persons: Father, Son, and Holy Ghost?
Because God has so revealed Himself in His Word, that these three distinct persons are the one, true, eternal God.
