Universalism=Placing all in the New Covenant, or New Heavens and Earth
When the Old Covenant ("heaven and earth") disappeared in 70 (Heb. 8:13), the fleshly ordinances (foods, drinks, baptisms) were abolished (Col. 2:16,17; Heb. 9:10), and the man-made temple-system was destroyed. However, the Law of the old covenant was not destroyed, but was fulfilled (Matt. 5:17). In fact, the Law of God is at the heart of the eternal, New-Covenant world. As Heb. 8:10,16 says:
"For this is the [New] Covenant that I will make with the house of Israel after those days, says the Lord; I will put my laws into their mind, and write them in their hearts" (Heb. 8:10).
According to the book of Hebrews, Christ cannot appear a third time. As Heb. 9:27 argues, as men die only once and are then judged only once, so Christ died for sins only once and was then to appear for salvation only once. A "third coming" is not a biblical option. The book of Hebrews further says that Christ's once-for-all Appearing for salvation was going to take place "in a very little while," "without delay" (Heb. 10:37), and that when He Appeared, the covenant mediated by Moses was going to "disappear" (Heb. 8;13) and "the way of the holy places" was going to be "manifested" (Heb. 9:8). Today the condemning old covenant is ancient history and we dwell securely in the heavenly places in our Redeemer. These things are realities today because of Jesus' once-for-all Appearing "for salvation" in A. D. 70.
