For we are his temple, collectively, and has individuals. For he ocndescends to dwell in the union of all and in each person. He is as great in the individual as he is in the whole body of his worshippers, for he cannot be increased in bulk or diminished by partition. When we lift up our hearts to him, our heart is his altar. We propitiate him by our priest, his only-begotten Son. We sacrifice blood-stained victims to him when we fight for truth "as far as shedding our blood." We burn the sweetest incense for him, when we are in his sight on fire with devout and holy love. We vow to him and offer to him the gifts he has given us, and the gift of ourselves.... We offer to him on the altar of the heart, the sacrifice of humility and praise, and the flame on the altar is the burning fire of charity. (Augustine, City of God 10.3; trans. Bettenson)
So, not only is the body, both individual and collective, the temple of God--and it can be both since God is indivisible and everywhere at once without being diminished in the individual or increased in the group--but the heart is the altar. Sacrifices are not only actual shedding of blood (reference is to Heb. 12:4), but also humility and praise. The incense is supplied by devout and holy love. And the fire of the altar is charity. To have your temple (yourself and your community) operating fully, therefore, you need a heart full of love, charity, praise, and humility. Ultimately, not a bad reading of Paul, especially 1 Corinthians.
