The Lord sees a mother weeping over the death of her son and has compassion on her; another time he was called to a marriage, and rejoiced together with the family. By this He showed that to share ordinary everyday joys and sorrows is not contrary to His spirit.
This is what true, reverent Christians do, who live their life in fear [of God]. However, they distinguish some everyday life routines from others; for much has entered into these routines which cannot be God’s good will. There are customs that come from passions, which arise for their indulgence; others are kept alive by vanity and busyness. He who has the spirit of Christ, will be able to distinguish the good from the bad: he adheres to the one and rejects the other.
