First off, baptism is our outward and visible sign of the death and birth as a new creation into Christ. But, even at that, it is still an act of new birth. We must "grow into the full stature of Christ." We are not born fully grown physically or spiritually.
Secondly, once we are baptized, we have citizenship in the Rule of God, but we may still choose to live in God's will or way. We may also continue to sin willfully, but that does not negate the power of baptism, only our refusal of the grace of new life.
We must grow up as little Christ's. As the church, we must bring up Christians in our life of worship, study, and recreation of the world. We see this clearly in bringing up children, but even for adults we may hide our immaturity, but we still desperately need to grow into life in Christ and his community.
The primary tools of our tradition are liturgical worship centered on the sacraments and daily offices, personal prayer, Bible study, and acts of charity and justice. The emphasis placed in each of these areas will vary from other Christian traditions, and these areas listed do not exhaust the tools of God or the church. Some other tools of formation may include rules of life, meditation or contemplation, ecstatic prayer, fasting, poverty, pilgrimage. In my life, I would add parenting and marriage as tools that God has used in my own maturing process.
But these tools are just the ways we live out our life as baptized members of the Body of Christ. Baptism is our birth and identity; from it and its promises flow our vocations and ministries in life and the church.
We are not born under the law. We are born into the world without the benefit of law, unless our parents bring us intentionally into the Rule (Kingdom) of God. That is the real mark of infant baptism, that the parents and godparents and community of the church are promising to bring a child up within the church and kingdom of God. That is why we don't rush that commitment.
But whether we are born in the wilds or in the house of God, we all learn quickly how to live in a world of sin. We sin; that is, we miss the mark of living into the purpose and desire of God for us. Often people wince at saying that children sin, but no one has to be taught how to hit or be selfish.
We are creatures who must be born of flesh and of water as Jesus told Nicodemus in John's Gospel. We sin, but we are able through the Spirit of God to return to our original purpose of living as God's image in the world (Genesis 2) and God's sons and daughters (John 1).
When we fail to live into that fullness of purpose, we are sinning. We have the law to guide us when we are young, and it is not done away with in Christ, as he said in Matthew 5, but rather it is fulfilled, and as we mature we no longer need it. This is just as it is in life. When we are young we are taught not to steal, but as we mature we no longer need to be told; rather our life moves to easy compliance with the law and then past that to generative creative giving. We no longer feel even desire to steal but rather we freely give to others knowing that as God's children we have all our needs fulfilled in Christ.
Our sins should, legally speaking, disqualify us from life in God because we have rejected and left God's purpose and desire for us. The news bears witness to our state as humanity, as a nation, as people. Our hearts bear witness to our own failures. If they do not, our families and communities can surely name our sins for us! We have not loved God or our neighbors as ourselves. We have done wrong and left good undone.
But God did not abandon us, but rather sent his Son a person of his own essence to bear our sins and death sentence and offer to us his own Rule of Life, new life and creation through his death and resurrection. We are made new in him. We join ourselves to him in baptism, being reborn. The consequences of our sins are then washed away. We are made free (redeemed) to choose to live in this new life and mature into the full stature of Christ.
This is where it begins. We weekly (or more) reenact our oneness in Christ in consuming his body and blood in the Eucharist, the thanksgiving meal and remembrance of passion and new life. We are made one again in the Lord's Supper, Mass, and Communion. But our entrance into a life in faith is the waters of baptism.
God in Christ
Fundamental to our claim as Christians is that we know God in the person of Jesus of Nazareth, the Christ, the Son of God. God is as Jesus revealed him through his life, teachings, death, and resurrection. God is as Jesus revealed him in his very being.
This is important. Jesus reveals God as a loving Father, who is pleased in Christ, and who is redeeming the world from sin and separation in Christ. God is not some terrible tyrant or impersonal force. God is love; self-sacrificial, self-giving, merciful, forgiving, and making new love. Jesus tells us that God intends for us to be like God in these ways. We are not merely to "believe in" God or Jesus.
We are meant to join our lives to God in Jesus, through baptism and eucharist, love and forgiveness, prayer and charity.
All of our speech about God is analogical, which any good book on theology (the formal study of thoughts about God) would point out. We have nothing to compare to God because God is uncreated and does not exist within the limits of the created order. So we have no pure language about God, we have only analogies. We have to use symbols and symbolic language to describe what we experience and come to know about God. And no image or symbol is perfect, which is why we are told to not make an image of God in the Ten Commandments.
As we come together this week, let's agree that we are joining in a conversation that is several thousand years old, and that our language is shaped by that long conversation and formed by the teachings and language of Jesus Christ. We trust his language first, but we can allow some breath too.
Let's be light with our conversation partners. Give each other permission to explore and listen carefully but with grace as we stretch to find expression for our own experiences and knowledge of God. Be kind and listen with a heart full of compassion. Don't try to correct each other, but just listen. Ask gentle questions, if questions arise, and trust the Holy Spirit to work in the process and in us.
