Inside the inner sanctuary he made two cherubim of olive wood, each ten cubits high. (I Kings 6:23) This was in the sanctuary of Solomon’s temple. Did the artisan(s) include sunglasses or perhaps sideburns on the Cherubim? What aesthetics were incorporated? Seeing this replacement for the tabernacle was done under the inspired leadership of Solomon, who can say? Because the people of God were forbidden to make “. . any likeness of anything that is in heaven above, or that is in the earth beneath. .” there is no record of the aesthetics. Who stands today with the inspiration of Solomon or Bezalel & Aholiab to build a temple? It is somewhat understandable concerning those who have not yet accepted Jesus as the Messiah. They might be inclined to try such a thing. But what can be said of those who claim to have accepted the blood of the everlasting covenant? They should know better.
To consider the idea of attempting to build a new temple is foolishness. It is to spit upon the sacrifice of Jesus. Christ died as the final and ultimate sacrifice for mankind. (Heb 9:23-28) Christ died to establish a better covenant. (Heb 8:7-13; 9:11-15) Christ died to establish a better and more glorious temple—His church. (Eph 2:19-22) A physical temple would spit upon what Christ paid for with his blood. (Acts 20:28) Just as Christ’s sacrifice was not a failure, The establishment of His church was not a “stop-gap/temporary” measure as many in “evangelical Christianity” would like to believe. Why not simply bow to Christ and His sacrifice and be concerned about the only temple of God that counts—His church?
As I mentioned, it is understandable for the Jews who have not yet accepted Jesus of Nazareth to want to rebuild the temple. (Not that is the right thing to do, but understandable.) But it is way out of bounds for the followers of Jesus to want to see such a thing, let alone support it.
We hope there are those who do not yet realize what they are doing, and will awaken.
Every notion of a third temple is fraught with difficulties. Difficulties of the priesthood (genetics can answer some questions, but not enough, not with certainty), difficulties of animal husbandry and cleansing rituals (the red heifer problem is a real problem, one of many), difficulties of finance, politics, and certain violence. Not that any of those kinds of issues have stopped men before in the pursuit of their own aims. As noted in another post here, there were false prophets among the people in prior ages, there can be again, with assurances of divine mandate that cater to the desires of the determined.
Let’s hope for friends and neighbors who are looking for an earthly temple, that they will reconsider and find their place in the spiritual temple.
