Blessed are the clean of heart, for they will see God. MT 5:8
Who can ascend the mountain of the LORD? or who may stand in his holy place? One whose hands are sinless, whose heart is clean, who desires not what is vain. PS 24:3-4
Saint John Paul II
And he gave some as Apostles, others as prophets, others as evangelists, others as pastors and teachers, to equip the holy ones for the work of ministry, for building up the Body of Christ, until we all attain to the unity of faith and knowledge of the Son of God, to mature manhood to the extent of the full stature of Christ, so that we may no longer be infants, tossed by waves and swept along by every wind of teaching arising from human trickery, from their cunning in the interests of deceitful scheming. Rather, living the truth in love, we should grow in every way into him who is the head, Christ. EPH 4:11-14
St. Mother Teresa of Calcutta
In the same way, anyone of you who does not renounce all his possessions cannot be my disciple. Lk 14:33
