Which of the following is one of the Beatitudes mentioned in Matthew?

The phrase "pure in heart" is indeed one of the Beatitudes found in the Gospel of Matthew, specifically in Matthew 5:8. This Beatitude emphasizes the importance of internal purity and integrity, suggesting that those who seek a clean heart—free from deceit and malice—are in a special relationship with God. The promise associated with this Beatitude is that the pure in heart will "see God," which highlights the spiritual rewards of seeking holiness and sincerity in one's life.

In contrast, the other choices represent concepts that are not aligned with the teachings of the Beatitudes. A strong and powerful king does not reflect the humble and countercultural nature of Christ's teachings. Wealthy and blessed is also misleading, as the Beatitudes often turn worldly values on their head, focusing instead on the blessedness of the poor in spirit. Lastly, fearful and afraid does not embody the comfort and assurance found in the Beatitudes, which invite followers to embrace hope and faith rather than fear.
