Well have you posted those verses. Consider this. There are two meanings of "spiritual":

1. The substance of the object is spirit - Like God (Jn.4:24), or like an angel (Ps.104:4)
2. The object has its ORIGIN in the Holy Spirit - like the spiritual gifts of 1st Corinthians 12

If we look at the verses you posted, see how many times the "bodies" of men is mentioned. That is, the Church is made of "bodies", so it is very real. Our Lord's first mention of the Church is connected with only two things: (i) the keys of the kingdom, and (ii) the Gates of Hades. Hades is the place of dead men, and dead men are men who have left their bodies to rot back to the elements. That is, the BODY of a man makes up the Church (1st Cor.6:15) and while death is the enemy of the Church, resurrection - the overcoming of the gates of Hades, to which Christ has the keys (Rev.1:18) is the solution. That is, the Church is only completed when all Chrstians are released from death, or when there is no more death for Christians.

But why then is it called a "Spiritual House"? Not because it is spirit in substance, but because it has its ORIGIN in the Holy Spirit. It starts with the rebirth (Jn.3:3-5) which only pertains to the spirit of man (Jn.3:6) by the Holy Spirit. Then the fallen and depraved soul of a Christian is "transformed" by the Holy Spirit (2nd Cor.3:18), and then lastly, on the day of resurrection, the same Holy Spirit will raise us from the dead, redeeming the BODY (Rom.8:11; Eph.1:13-14). As long as men are in their bodies, and have experienced the rebirth, the Church really exists.

God has chosen to operate His work from the basis of faith. Romans 8:2, Hebrews 11:6

It is by "Grace" through "Faith (in Christ and the Cross)" that the "Temple" is built. Galatians 2:20-21

The only thing that God will accept from any Believer is "Faith" in His Beloved Son Jesus and the Cross of Calvary where the victory was won, i.e., The Finished Work, i.e., The Blood of Jesus. Romans 8:2, 1 Cor. 2:2

I always understood that the Church was built by

1. Resurrection (Matt.16:17-18)
2. bThe right materials - gold, silver and precious stones (1st Cor.3)
3. The gifted ones in the Church (Eph.4)
4. The sincere milk of the Word (1st Pet.2)
