Baptism is not only a sign of profession and mark of difference whereby Christians are distinguished from others that are not baptized; but it is also a sign of regeneration or the new birth. The Baptism of young children is to be retained in the Church.
The change from Christian men to Christians is simply to be more gender-neutral. In the Episcopal formulation baptism (even of infants) is considered a sign of entry into the Church. There is some doubt whether infant baptism is most agreeable with the institution of Christ or simply an accepted practice.
XXVII. Of Baptism.
Baptism is not only a sign of profession, and mark of difference, whereby Christian men are discerned from others that be not christened, but it is also a sign of Regeneration or New-Birth, whereby, as by an instrument, they that receive Baptism rightly are grafted into the Church; the promises of the forgiveness of sin, and of our adoption to be the sons of God by the Holy Ghost, are visibly signed and sealed, Faith is confirmed, and Grace increased by virtue of prayer unto God.
The Baptism of young Children is in any wise to be retained in the Church, as most agreeable with the institution of Christ.
