Sunday evening service, looking at the Heidelberg Catechism, or the Orthodox Catechism, Lord's Day 8 - #24-25 Q. HOW ARE THESE ARTICLES (THE APOSTLES' CREED) DIVIDED? A. Into three parts: the first is about God the Father and our creation; the second, about God the Son and our redemption; the third, about God the Holy Spirit and our sanctification. Q. SINCE THERE IS ONLY ONE GOD, WHY DO YOU SPEAK OF THREE: FATHER, SON, AND HOLY SPIRIT? A. Because God has so revealed Himself in His Word, that these three distinct Persons are the one, true, eternal God.
