Making the sign of the cross (Latin: signum crucis), also known as blessing oneself or crossing oneself, is a ritual blessing made by members of some branches of Christianity. There are three variants of the sign of the cross, including a large sign of the cross made across the body, a small sign of the cross traced on the forehead or objects, as well as a lesser sign of the cross made over the forehead, lips and heart.[1][2][3][4][5][6]
The use of the sign of the cross traces back to early Christianity, with the third-century treatise Apostolic Tradition directing that it be used during the minor exorcism of baptism, during ablutions before praying at fixed prayer times, and in times of temptation.[7]
The large sign of the cross is made by the tracing of an upright cross or Greek cross across the body with the right hand, often accompanied by spoken or mental recitation of the Trinitarian formula: "In the name of the Father, and of the Son, and of the Holy Spirit. Amen."[5][8][9] The movement is the tracing of the shape of a cross in the air or on one's own body, echoing the traditional shape of the cross of the crucifixion of Jesus. Where this is done with fingers joined, there are two principal forms: one—three fingers (to represent the Trinity),[10] right to left—is exclusively used by Christians who belong to the Eastern Orthodox Church, the Church of the East, Eastern Lutheran Churches and the Eastern Catholic Churches in the Byzantine and Syriac Christian traditions; the other—left to right to middle, other than three fingers—used by Christians who belong to the Latin Rite of the Catholic Church, Lutheranism, Anglicanism and Oriental Orthodoxy. The large sign of the cross is used in some denominations of Methodism and within some branches of Reformed Christianity.
The use of the small sign of the cross has been documented in early Christianity by Tertullian, an Ante-Nicene Church Father, who wrote in AD 204 in De Corona ('On Crowns'): "In all our actions, when we come in or go out, when we dress, when we wash, at our meals, before retiring to sleep we form on our foreheads the sign of the cross."[3][11][12] Tertullian attested to the Christian practice of tracing this small sign of the cross on objects, such one's bed before sleeping.[3] It is traced on the forehead, or objects, with the thumb (sometimes using holy water or anointing oil).[1][13][4][3] The small sign of the cross is made on the forehead during the rites of baptism and the anointing of the sick in Catholicism, Lutheranism and Anglicanism.[13][14][1][15] In the Baptist, Methodist, and Pentecostal traditions of Christianity, the small sign of the cross is often made on the forehead of the recipient during ordinations, anointing of the sick and deliverance prayers.[16][17] Christians of various denominations have traced the small sign of the cross onto doors or windows of their dwellings as a house blessing.[18][19][20] The small sign of the cross is additionally used during certain observances, such as during the imposition of ashes on Ash Wednesday, in which ashes are marked on the forehead of a believer using the small sign of the cross.[21][22][23]
Many individuals use the expression "cross my heart and hope to die" as an oath, making the sign of the cross, in order to show "truthfulness and sincerity", sworn before God, in both personal and legal situations.[24]
The BCP directs that the celebrant at baptism will make the sign of the cross on the forehead of the candidate for baptism (using chrism if desired), saying "You are sealed by the Holy Spirit in Baptism and marked as Christ's own for ever" (BCP, p. 308). In the form for Ministration to the Sick the BCP directs that if the sick person is to be anointed, the priest dips a thumb in the holy oil and makes the sign of the cross on the sick person's forehead (BCP, p. 456). The BOS provides that at the admission of catechumens, each catechumen is presented by name to the celebrant who marks a cross on the forehead of each with a thumb, saying "Receive the sign of the Cross on your forehead and in your heart, in the Name of the Father, and of the Son, and of the Holy Spirit."
It's generally accepted that unitl the fourth century, Christians traced a small sign of the cross on their foreheads. Either boasting or lamenting Tertullian attested, "We Christians wear out our foreheads with the sign of the cross." However, Tertullian also revealed the practice of "signing" the cross on objects like the woman who made the sign of the cross on her bed before retiring at night. By the fourth century the small sign extended to several parts of the body
A small sign of the cross can be traced on the forehead of a child or upon an object which you wish to bless.
As early as the beginning of the third century in Africa and at Rome, the making of a sign of the cross on the forehead during the rites of initiation seems already to be a traditional way of showing that the person belonged to Christ and to be regarded as a kind of invisible seal; Christians also made the sign of the cross on themselves rather frequently. It was then extended to the various senses and became an exorcistic gesture. Another form of the sign of the cross is the gesture of blessing, made either with all the fingers extended and joined or with some fingers extended and the others closed; the manner varied according to the practice of different Churches and different periods, and was also influenced by allegorical considerations; Easterners have often been accustomed to giving a blessing while holding a cross. Finally, the large sign of the cross (forehead to breast to shoulders) that is familiar to modern believers seems of relatively late origin

The large sign of the cross made over the body, as we make it today, originated in the East between the fifth and eighth centuries, but there is no satisfactory evidence of its use in the West until the thirteenth century.
There is another gesture done at our Baptism, one that we know very well. [The catechist makes a small sign of the cross with her thumb on the forehead at each child.] (The children readily recognize the cross). At our Baptism the priest and also our parents and godparents make this sign on us. They use their thumb, the strongest finger to make this sign on us to show that this is meant to go deep into our heart. This sign marks us as a sheep of the Good Shepherd.
During the rite of Baptism, Christians may receive a bodily anointing, when the forehead is anointed with oil in the sign of the cross. This bodily anointing likewise signifies our incorporation into Christ.
394 A lay minister traces the sign of the cross on the forehead of each sick person and says the following prayer of blessing.
...take the anointing oil and over every window and door to your house just put the sign of the cross in the corner of it.
Then I took exorcized oil and made a sign of the cross on the door, windows, and lintels.
