In the second reading for Sunday's liturgy Paul tells the Corinthians:

Do you not know that you are the temple of God, and that the Spirit of God dwells in you? If anyone destroys God's temple, God will destroy that person; for the temple of God, which you are, is holy.

Centuries later John Henry Newman concluded a sermon to his congregation with these words:

It is our concern only to look to ourselves, and to see that, as we have received the gift, we "grieve not the Holy Spirit of God, whereby we are sealed unto the day of redemption;" remembering that "if any man destroy the temple of God, him shall God destroy." This reflection and the recollection of our many backslidings, will ever keep us, please God, from judging others, or from priding ourselves on our privileges. Let us but consider how we have fallen from the light and grace of our Baptism. Were we now what that Holy Sacrament made us, we might ever ''go on our way rejoicing;" but having sullied our heavenly garments, in one way or other, in a greater or less degree (God knoweth! and our own consciences too in a measure), alas! the Spirit of adoption has in part receded from us, and the sense of guilt, remorse, sorrow, and penitence must take His place. We must renew our confession, and seek afresh our absolution day by day, before we dare call upon God as "our Father," or offer up Psalms and Intercessions to Him. And, whatever pain and affliction meets us through life, we must take it as a merciful penance imposed by a Father upon erring children, to be borne meekly and thankfully, and as intended to remind us of the weight of that infinitely greater punishment, which was our desert by nature, and which Christ bore for us on the Cross.
