NOTICE: While going through these lessons, please realize that they are missing the perspective of HOLYDAYS 2 & 3 being the next BIG EVENTS on earth - not the return of Christ on HOLYDAY 4.
These are old lessons from the Worldwide Church of God under Herbert W. Armstrong's (HWA) leadership (1934-1986). HWA was not given the insight into Holydays 2 & 3 and their connection to Revelation 4 & 5. And HWA eventually corrected the observance of Pentecost from Monday to Sunday after the word "from" was understood to mean "from and including" (Lev 23:15). And Passover was never observed as the first Holyday of the seven days of the Feast of Unleavened Bread. This was a major mistake, and I believe this mistake kept the true church from understanding the purpose and still pending fulfillment of Holydays 2 & 3.
