The Holy Scriptures is a set of three volumes of True Parents' messages—the Cheon Seong Gyeong, the Pyeong Hwa Gyeong and the Cham Bumo Gyeong—the Cham Bumo Gyeong being the latest volume now available for purchase.
The Cheon Seong Gyeong is a collection of internal guidance given by True Parents.
The Pyeong Hwa Gyeong is a compilation of True Parents' messages on world peace given around the globe throughout their ministry.
The Cham Bumo Gyeong details True Parents' life course in their own words, going deeper into the meaning of True Parents' work and vision.
The Holy Scriptures constitute an unparalleled body of work for families to study as part of their daily devotion, what Unificationists call Hoon Dok Hwe. Many Unificationist families devote time to reading them early in the morning before they begin their daily routine. You can purchase the Holy Scriptures individually or as a set.
