If one will consider the common understanding of the word MOJON, it symbolizes the monument that determines the boundary of lots or land to another adjacent lot. It symbolizes to what measurement a man’s land is identified. Likewise it identifies the exact boundary of the land properties. On the spiritual side of its history, Mojon have chosen San Andres to be its patron saint, emulating the life of the apostle of Jesus, his virtues and his devoted service to Him. He is the older brother of St. Peter, another faithful apostle of Jesus. He was born in Bethsaida, Galilee. He is the first apostle to know Jesus and established a personal relationship with Him. When our Lord was crucified and died in the cross, San Andres was designated to be in charge of a province named Seitia to spread and propagate the good news of the Lord. As a consequence of his devoted service he was able to recruit followers of the Lord. Egeas, a very powerful man during his time, ordered his arrest and detention. He was tortured and subjected to severe punishment. The people resented this and threatened rebellion if San Andres will not be freed, so Egeas, ordered his release. But everyone who unties his hands loses strength, but finally he was a free man.. Because of his love for Jesus he himself carried the cross until his death, and before he died he uttered his words, “it is already the time I must go to you, and brightness surrounded his body. The people of Mojon, continued to live a life full of devotion of the patron saint.
