When speaking of any sacrament, we speak of matter (actions done, objects used) and form (words pronounced). The definition of a sacrament is a visible sign, instituted by God, to confer grace. This is how the word "sign" is used in respect to sacraments.
The sign or sacrament of baptism is the initial sacrament of the Church through which a soul is cleansed of Original Sin and becomes a living member of Mystical Body of Christ and therefore able to enter into heaven. It is the rite of Christian initiation.
If by sign, an image or symbol is inferred, then a candle, a white gown or perhaps a shell holding or pouring water (an artistic device often used by painters portraying St. John the Baptist) could be employed.
A cross is used in a baptism as a sign of love and respect
a dove
Similarites being the water baptism is a physical act and the baptism of desire is not the way that Jesus was baptized. Rather the desire is actually a desire to not have to do more than just think about baptism.
Baptism
No, baptism is a concrete noun. It refers to the physical act of immersing someone in water or sprinkling water on them as a religious ritual.
Infant baptism is based on the belief that baptism is a sign of God's covenant with believers, similar to circumcision in the Old Testament. Some Christians argue that since infants were included in the covenant in the Old Testament, they should also be included in the covenant of baptism in the New Testament.
Jesus was baptized by John in the river Jordan, but the holy spirit descended on him in the form of a dove.
Baptism is a sign of repentance, washing and renewing. It signifies repenting of one's sin, being cleansed by God of that sin, and a visual sign and testimony of faith in Christ Jesus. Why certain denominations therefore baptise as infants beats me...
I am not sure what is meant by "connect you with God". However, what we can say is that baptism reminds you of God's love and grace for you, a sign that you are "special" to God. If we considered a baptized person B and an unbaptized person U, both are equally loved by God. B, though, has had a physical experience that can remind them of this while U has not. B of course could ignore this reminder, and what we must not say is that the baptism in and by itself "made" God love B.
Yes, in Christian theology, baptism is often seen as replacing circumcision as a sign of initiation into the faith. Both practices symbolize a covenant relationship with God, but baptism is considered the New Testament equivalent in Christianity.
What baptism are you talking about? Infant baptism? Baptism of believers? Well the answer is much the same. Nothing happens to your sin when you are baptized. If you are a believer your sin is already dealt with before you get baptized. A believers baptism is a sign of the believers identifying with Christ in that Christ was buried and rose again the believer is buried (in water) and rises again to a new life. Infant baptism??? well there is nothing in the Bible that teaches infant baptism.
Water is used in baptism to symbolize the cleansing from sin given by the free grace of God.
