Baptismal font in the context of "Florence Baptistery"

Infant baptism, also known as christening or paedobaptism, is a Christian sacramental practice of baptizing infants and young children. Such practice is done in the Catholic Church, the Eastern Orthodox and Oriental Orthodox churches, various Protestant denominations, and also in other denominations of Christianity. The practice involves baptizing infants born to believing parents as a means of initiating them into the Christian faith. Supporters of infant baptism cite biblical references to the baptism of entire households in the New Testament, as well as Jesus' teachings on welcoming children, as justification for this approach.

In contrast, believers' baptism (credobaptism) is based on the premise that baptism should be administered only to individuals who can personally profess their faith. Those who support this view argue that baptism is a conscious act of commitment to Christianity, requiring an understanding of its significance. As a result, they maintain that only those capable of articulating their belief should participate in the sacrament. This perspective is commonly held by Anabaptists, Baptists, Pentecostals, and other evangelical groups. Proponents of believers’ baptism argue that the absence of explicit references to infant baptism in the New Testament, along with the significance of baptism as a personal commitment.

A sacristan is an officer charged with care of the sacristy, the church, and their contents.

In ancient times, many duties of the sacrist were performed by the doorkeepers (ostiarii), and later by the treasurers and mansionarii. The Decretals of Gregory IX speak of the sacristan as if he had an honourable office attached to a certain benefice, and say that his duty was to care for the sacred vessels, vestments, lights, etc. Nowadays the sacristan is elected or appointed. The Cæremoniale Episcoporum prescribed that in cathedral and collegiate churches the sacristan should be a priest, and describes his duties in regard to the sacristy, the Blessed Eucharist, the baptismal font, the holy oils, the sacred relics, the decoration of the church for the different seasons and feasts, the preparation of what is necessary for the various ceremonies, the pregustation in pontifical Mass, the ringing of the church bells, the preservation of order in the church, and the distribution of Masses; finally it suggests that one or two canons be appointed each year to supervise the work of the sacrist and his assistants.

In Christian architecture the baptistery or baptistry (Old French baptisterie; Latin baptisterium; Greek βαπτιστήριον, 'bathing-place, baptistery', from βαπτίζειν, baptízein, 'to baptize') is the separate centrally planned structure surrounding the baptismal font. The baptistery may be incorporated within the body of a church or cathedral, and provided with an altar as a chapel. In the early Church, the catechumens were instructed and the sacrament of baptism was administered in the baptistery.

The Sigurd stones form a group of eight or nine Swedish runic inscriptions (five or six runestones, two natural rocks, and a baptismal font) and one picture stone that depict imagery from the Germanic heroic legend of Sigurd the dragon slayer. They were made during the Viking Age and constitute the earliest Norse representations of the matter of the Völsung cycle that is the basis of the Middle High German Nibelungenlied and the Sigurd legends in the Poetic Edda, the Prose Edda, and the Völsunga saga.

In addition, the figure of Sigurd sucking the dragon's blood from his thumb appears on several carved stones in parts of Great Britain with strong Scandinavian cultural influence: at Ripon and Kirby Hill, North Yorkshire, at York and at Halton, Lancashire, and carved slates from the Isle of Man, broadly dated c. 950–1000, include several pieces interpreted as showing episodes from the Sigurd story.

St James's Church, Piccadilly, also known as St James's Church, Westminster, and St James-in-the-Fields, is an Anglican church on Piccadilly in the centre of London, England. The church was designed and built by Sir Christopher Wren.

The church is built of red brick with Portland stone dressings. Its interior has galleries on three sides supported by square pillars and the nave has a barrel vault supported by Corinthian columns. The carved marble font and limewood reredos are both notable examples of the work of Grinling Gibbons. In 1902, an outside pulpit was erected on the north wall of the church. It was designed by Temple Moore and carved by Laurence Arthur Turner. It was damaged in 1940, but restored at the same time as the rest of the fabric.
