Small columbidae are generally called doves and larger ones are usually called pigeons. Why is the Holy Spirit pictured as descending like a dove in Mark 1:9-15? In the Old Testament Noah sent a dove to test if it was time to exit the ark (Genesis 8:8-12). In the same manner, the Holy Spirit lets us know when things are right. David sang of flying away on the wings of a dove to find rest (Psalm 55:6). In the same manner the Holy Spirit takes us to a place of rest. Solomon sang of his love being undefiled like a dove (Song 5:2; 6:9). In the same manner he is called the Holy Spirit. A dove was considered to be harmless (Matthew 10:16). In the same way the Holy Spirit wishes us no harm.
