The Apostle Peter’s reaction to the Transfiguration reveals that he was overwhelmed by his firsthand experience of a glimpse of Jesus’ true glory. Not long before this moment, our Lord took His disciples north to Caesarea Philippi and asked them privately who they thought He was. Peter boldly proclaimed, “You are the Messiah, the Son of the living God” (Matthew 16:16). In response, Jesus promised Peter that He would build His Church upon him and that Peter himself would be entrusted with the keys to the Kingdom of Heaven. It was a good day for Peter. Shortly after this, however, Jesus began to reveal to His disciples that He “must go to Jerusalem and suffer greatly from the elders, the chief priests, and the scribes, and be killed and on the third day be raised” (Matthew 16:21). In response, Peter pulled Jesus aside and said, “God forbid, Lord! No such thing shall ever happen to you” (Matthew 16:22). Jesus replied harshly to Peter’s rebuke: “Get behind me, Satan! You are an obstacle to me. You are thinking not as God does, but as human beings do” (Matthew 16:23). It was a bad day for Peter. Jesus then taught His disciples, “Whoever wishes to come after me must deny himself, take up his cross, and follow me. For whoever wishes to save his life will lose it, but whoever loses his life for my sake will find it” (Matthew 16:24–25). Not only was Jesus soon to suffer greatly, but His followers, including the Twelve, were called to follow Him on this difficult path. This was hard news for them to accept. In today’s Gospel, we hear the story of the Transfiguration. Interestingly, Jesus allowed the disciples to reflect on His prediction of suffering for six days before taking Peter, James, and John up a mountain for prayer and solitude. Jesus, aware of their confusion and struggles, was transfigured before their eyes. “His face shone like the sun and his clothes became white as light. And behold, Moses and Elijah appeared to them, conversing with him” (Matthew 17:2–3). Peter exclaimed in this moment of glory, “Lord, it is good that we are here.” It was another good day for Peter. We all have good days and bad days. But what defines a good day versus a bad day? Was the day of Jesus’ Crucifixion a bad one for Him? Certainly not. Though filled with intense suffering, it was the most glorious day in history because His perfect obedience to the Father’s will was fulfilled. Similarly, Peter’s good and bad days can be understood in terms of his willingness to obey Christ, especially when the demands were great. In our lives, we must also define our good and bad days through the lens of obedience to God’s will, especially when His will calls us to bear the Cross and practice sacrificial love. It’s easy to love God when we are consoled, but it becomes much more difficult when we face trials. Peter’s declaration, “Lord, it is good that we are here,” is the perfect prayer for us to echo in every circumstance. When we are consoled, as Peter was at the Transfiguration, we must pray this prayer. But unlike Peter’s earlier missteps, we must also say, “It is good,” when we encounter opportunities for sacrificial love, even when difficult. Reflect today on your own good and bad days. Use the lens of holy obedience and your call to live a life of sacrificial love. Do not hesitate to cry out to the Lord, “It is good!” Consider whether you view every cross and every invitation to love sacrificially as something good. This is what God desires for you; embrace His desire with determination and joy. My sacrificial Lord, You embraced the Cross and saw it as truly good. You looked beyond the suffering and saw the fruits of Your sacrifice. Help me to imitate You by seeing every act of sacrificial love as the good I desire. I love You, Lord. Help me to love You and others with all my heart. Jesus, I trust in You.
