And I saw no temple in the city, for its temple is the Lord God the Almighty and the Lamb. And the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb. (Revelation 21:22-23, ESV)
Here is Joseph Mangina’s commentary on the wondrous passage above:
The vision reaches its surprising climax in John’s report of something he does not see, namely, a temple. The city has no need of a temple, “for its temple is the Lord God the Almighty and the Lamb.” Their radiance is such that even the illumination provided by sun and stars is superfluous. Special sacraments are no longer necessary, because in the new eon “all truth will be openly and perfectly revealed” (Aquinas, Summa theologiae). The life of the city will not point to God, it will be in God. But John’s remark that “[the city’s] lamp is the Lamb” permits us to say something St. Thomas does not: in the age to come, the vision of God will be mediated through the risen, glorified flesh of Jesus. The heavenly city is not the end of the church, for the church is simply God’s people. It is, however, the end of religion, the demarcation of sacred space from profane space and liturgical time from ordinary time, for the purpose of making present the absent god.
