God didn't only let us see his humanity through Christ, but wanted to bring back the humanity of each man to the faithful expression of the first couple, made in the image of God the Creator. In Christ, every man and woman is brought back to the original capacity to make visible the image of God in this world. The letter to the Romans moves in this direction: "For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren." (Romans, 8:29). God's plan therefore aims to restore his image in man, offering in Christ the visible model of the new humanity.
The new man, the divine image restored in man, born from the consecration of thought, which takes place through the Word of God infused into the mind. The external behavior of the person could easily replicate the mode of Christianity, just as it would not be difficult to be mistaken for Muslims or Buddhists, having thoroughly studied and practiced their customs. But that does not mean they are Muslim or Buddhist. The being is in fact something deeper than the act. You can hire a behavior but not the spirit of it. You may decide to take some time to volunteering and caring for the poor, while maintaining a hidden contempt towards the assisted; this shows you can act like you love what you're doing without having it in your heart. You can go to the Sunday Mass but without faith. That's why the Apostle to the Ephesians says that the man must be renewed before all in the mind (Eph 4:23). It isn't enough and often it constitutes a very thin deception, to renew you only in the behavior. The Christian experience is not just reason and will. It would be simplistic to think so. The emotional sphere is an integral part of the human person, and as such cannot stay out of the renewal process operated by the grace of baptism. Especially since the feeling is a blind and passionate force who can lead the man astray, if he is not balanced and healed by the love of God. The Apostle Paul in Philippians 2:5 makes it clear that Jesus, as man, had his feelings; indeed, only if Christ's feelings stay in the heart of the Christian, you can have a healed and rebalanced passion. "Whoever says he abides in him ought to walk in the same way in which he walked." (John, 2:6)
Here the reference is undoubtedly to the lifestyle of Jesus as a man. With the verb "to walk", the Apostle did not intend to say that the Christian should imitate Jesus in the external aspects of his act. The Christian is not related to a code of laws, nor with a list of behaviors that "make" the Christian. The Christian is to be in force for a lifestyle that replicates that of the Master. But what does it mean exactly "replicate the lifestyle of the Master"? In the teaching of the New Testament, to imitate the life of Jesus is not to reproduce the appearance of the behaviors of the Son of God, but about assuming that model, assimilating the inner motivations that have pushed the Christ to act in one way and not in another. Jesus invites his disciples to imitate him in the provisions of his soul rather than in outward behavior, since the man is purified or contaminates from the content of his heart. This is what I try to do; I might not follow all the time the lifestyle of a Catholic, meaning that I don't always go to church for example, but I try to live taking Jesus as example; I try to keep my heart pure, I try to do well and treat everyone as my brothers and sisters. I think it's important to do so even with
