ISB ~ Matthew 5 v8

the pure in heart:Those who act with integrity and serve the Lord unselfishly. In biblical terms, the heart is the hidden center of the person where one’s thoughts, words, actions, and emotions are said to originate. A pure heart is undefiled by evil and lustful thoughts (5:27-30; 15:18-20) and finds its true treasure in heaven (6:19-21). In eternity, the pure in heart will see God as the angels do even now (18:10; 1 Cor 13:12; Rev 22:4). Catholic theology calls this unmediated union with God in heaven the Beatific Vision (CCC 2517-19).
