Good words from Origen about our being a spiritual house….
“All of us who believe in Jesus Christ are said to be “living stones” according to the statement of scripture when it says: “Like living stones be yourselves built into a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ” (1Pt 2,5).
We have learned to notice in the case of material stones, that those which are stronger and more powerful are placed first in the foundations, so that the weight of the whole building can be put securely on them. The stones that follow, of slightly inferior quality, are set close beside the foundation stones according to the weight carried by these stones… until they reach the roof. Similarly you must understand that from among these living stones there are some in the foundations of this spiritual building. Now who are those who are laid in the foundations? “The apostles and the prophets.” This is what Paul himself has to say in his teaching, “You are built upon the foundation of the apostles and prophets, Christ Jesus himself being the corner stone” (Eph 2,20).
You must learn that Christ also himself is the foundation of the building which we are now describing, so that you may more eagerly prepare yourself for the construction of his building and be found to be one of those stones which are closer to the foundation. For these are the words of Paul the apostle: “For no other foundation can anyone lay than that which is laid, which is Christ Jesus” (1Cor 3,11). Blessed therefore are those who will be found to have constructed sacred and religious buildings upon that glorious foundation!”
