A sponsor or sponsors (godparents) give a public profession of faith on behalf of the child being baptized, who is expected to ratify later the profession made on his or her behalf; and pedobaptists have no doubt that by baptism a child is cleansed from sin by the blood of Jesus and is symbolically buried with him and raised as a new person to life eternal.

Pedobaptists believe that if baptism is a sign that a person is a member of God's covenant community, and if the children of believers are members of that community, it follows that the children of believers should receive the sign that they are members of God's covenant community by being baptized.

A person who practices, adheres to, or advocates infant baptism: Mr. and Mrs. Jones wanted to have their good neighbor, a pedobaptist, to christen their little newborn baby.
