Thinking about the holy scriptures and how a Crucifix is useful as well as instructional it is worth looking at these passages
Blessings on him who comes in the name of the Lord. Jesus went on ahead, going up to Jerusalem. When he drew near to Bethphage and Bethany, at the mount that is called Olivet, he sent two disciples, saying, ‘Go into the village opposite, where on entering you will find a colt tied, on which no one has ever yet sat; untie it and bring it here. If anyone asks you, “Why are you untying it?” you shall say this, “The Lord has need of it.” So those who were sent went away and found it as he told them And as they were untying the colt, its owners said to them, “Why are you untying the colt?” And they said, “The Lord has need of it.” And they brought it to Jesus, and throwing their garments on the colt they set Jesus upon it. As he rose along, they spread their garments on the road. As he was drawing near, at the descent of the Mount of Olives, the whole multitude of the disciples began to rejoice and praise God with a loud voice for all the might works they had seen, saying, “Blessed is the King who comes in the name of the Lord! Peace in heaven and glory in the highest!” And some of the Pharisees in the multitude said to him, “Teacher, rebuke your disciples.” He answered, “I tell you, if these were silent, the very stones would cry out.”
Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
Those passages teach us that the Lord has not saved us by his triumphal entry or by means of powerful miracles. The Apostle Paul, in the second reading, epitomises in two verbs the path of redemption: Jesus “emptied” and “humbled” himself (Phil 2:7-8). These two verbs show the boundlessness of God’s love for us. Jesus emptied himself: he did not cling to the glory that was his as the Son of God, but became the Son of man in order to be in solidarity with us sinners in all things; yet he was without sin. Even more, he lived among us in “the condition of a servant” (v. 7); not of a king or a prince, but of a servant. Therefore he humbled himself, and the abyss of his humiliation, as Holy Week shows us, seems to be bottomless. God’s way of acting may seem so far removed from our own, that he was annihilated for our sake, while it seems difficult for us to even forget ourselves a little. He comes to save us; we are called to choose his way: the way of service, of giving, of forgetfulness of ourselves. Let us walk this path, pausing in these days to gaze upon the Crucifix; it is the “royal seat of God”. I invite you during this week to gaze often upon this “royal seat of God”, to learn about the humble love which saves and gives life, so that we may give up all selfishness, and the seeking of power and fame. By humbling himself, Jesus invites us to walk on his path. Let us turn our faces to him, let us ask for the grace to understand at least something of the mystery of his obliteration for our sake; and then, in silence, let us contemplate the mystery of this Week.
