The law brought a sense of rigor, while the gospel introduces grace; there, disbelief engenders fear, whereas here, the gift of grace flows abundantly for the faithful.
While our Lord and Saviour traversed numerous towns and regions, preaching and curing every ailment among the populace, “when He saw the crowds,” as the current passage recounts, “He ascended the mountain.” It is fitting for the exalted Lord to visit a high place to proclaim lofty truths to those eager to rise to virtue’s summit. Likewise, it is appropriate for the new Law to be proclaimed from a mountain, as the Mosaic Law was similarly given from heights. The former consisted of ten directives to guide and order life in this world, while the latter comprises eight beatitudes, guiding its followers toward eternal life and their heavenly homeland.
To bestow the heavenly benediction upon His disciples, the Lord ascended the mountain alongside them, as captured in the Gospel’s narration: “And going up,” it states, “on the mountain with the disciples, and extending His hand toward them, Jesus said, ‘Blessed are the poor in spirit, for yours is the kingdom of God’” (Luke 6:20). It was not without significance that our Lord and Saviour chose to bless His disciples on the mountain—above, rather than below. Hence, if one desires to receive heavenly blessings from the Lord, he must ascend the mountain, which signifies the pursuit of a life elevated toward heavenly ideals; only then will the desired blessings be granted justly and rightly. Conversely, remaining preoccupied with worldly matters will hinder the ability to receive blessings from the Lord. This is why it is stated, “The Lord is the God of the mountains and not the God of the valleys.”
Yet, it is essential to recognize that God is indeed the God of every locale and creature, as He is the Creator and Master of all. Nevertheless, the prophet's proclamation that “the Lord is the God of the mountains and not the God of the valleys” conveys a deep and spiritual truth. God humbles Himself to be the God of those who strive toward Him, like mountains, through the faith of their merits—all the holy individuals exemplify this. Mountains symbolize the patriarchs, prophets, apostles, and martyrs, thereby illustrating that our God is the deity of all these sanctified individuals. Thus, we find the pronouncement of the Lord, “I am the God of Abraham, and the God of Isaac, and the God of Jacob.” This is complemented by the affirmation that “God is not the God of the dead, but of the living.” In contrast, God does not condescend to be “the God of the valleys,” which represents sinful and unfaithful individuals dwelling in lowliness. Therefore, the wicked sinners do not merit having our God identified with them, for they lack belief in Him or knowledge of Him, whether due to pride or ignorance. While, by His divine nature, He is the God of all created beings due to His role as their Creator, His grace and willingness to be their God is reserved for those who adhere to His commandments and maintain their faith.
Finally, the mountain where the Lord conferred blessings upon His disciples foreshadows the image of the Church. The Church is likened to a mountain as it resides in exalted realms, triumphantly standing above the earthly domain—not due to the weight of stones, but through the sanctity of its existence. If you wish to be convinced of the appropriateness of designating the Church as a mountain, consider what Holy Scripture states: “Who shall ascend the mountain of the Lord, or who shall stand in His holy place?” For it cannot be asserted of any earthly mountain, “Who shall ascend the mountain of the Lord?” since such natural elevations are easily climbed by both humans and beasts. Rather, it is aptly said of the Lord's mountain, the heavenly mountain, or the holy Church, that only the blessed shall ascend to its faith and elevated life. Ascending such a mountain requires not bodily effort alone, but the faith of an inwardly renewed spirit.
Let us therefore remain steadfast on this mountain through elevated faith and spiritual action, so that we may receive from the Lord the blessings of the Gospel, which declare, “Blessed are you poor in spirit, for yours is the kingdom of God,” and so forth.
