The Christian sign of the cross as done by the faithful and clergy, did not come from “nowhere”. Likewise, as most of our ritual practices do, it holds deep symbolism and even expression of dogma itself. I will very briefly here outline the history and development of the sign of the cross throughout Church history, starting in the 2nd century.
The first known mention about the sign of the cross can be found already in the 2nd c. in the writings of Tertullian who wrote: “we mark our foreheads with the sign of the cross”[1]. We not only have information from Tertullian that the sign of the cross was used, but also how it was used: “We Christians wear out our foreheads with the sign of the cross”[2] which suggest to us that the sign of the cross was done on the forehead. Most point to the fact that the sign of the cross was done on the forehead with one finger, to symbolise the oneness of God as Jews and many pagans accused the early Christians of being polytheistic.
Likewise, in the same way the sign of the cross (in blessing form) was made on items, this can be read in the life of St. Barbara: “[Barbara] said, In the name of the Father, the Son and the Holy Spirit, and she miraculously drew the sign of the cross in the marble wall of the bathhouse with her finger (singular, one finger)”[3]. St. Epiphanius also confirms that the sign of the cross was early on in the history of the Church made with one finger[4]. The one finger sign of the cross can be seen up until the fourth century when we start to notice in writings that more than one finger was used for the sign of the cross. Instead the use of two fingers started to appear, most likely as a response and guard against Monophysitism – two fingers now symbolised the two natures of Christ. St. Cyril of Jerusalem remarks in his Catechesis (13:36) that the sign of the cross was to be made with “fingers”, plural. Theodoret of Cyrus, who was involved in rebuking and debating the Monophysics in the 5th century, wrote: “Thus does one bless with the hand and cross oneself: Holding three fingers together evenly the thumb and the last two fingers-confesses a mystery in the image of the Trinity (…) Joining two fingers together-the index and the middle finger-and extending them, with the middle finger slightly bent, represents the two natures of Christ: His Divinity and His Humanity”. This practice of the sign of the cross prevailed for many centuries.

In the 8th century, St. Peter Damascene wrote in what today is found in the Philokalia the following: “The Holy Fathers have handed down to us the meaning of this holy sign, in order to refute heretics and unbelievers. The two fingers and the one hand then, represent then the crucified Lord Jesus Christ, who we profess as having two natures in one person”[5]. It is however important to note that Sts. Cyril and Damascene as well as Theodoret were all a part of the local Church of Antioch. This local church was very active in the fight against Monophystitism and this view on the sign of the cross was defended there stoutly as a direct result of the Monophysite heresy. This fact makes it more likely that this sign of the cross, with two fingers, was not a universal practice of the Church as such, or at least this possibility needs to be accepted. As this tradition was prevalent in the Orthodox east (Cappadocia and Asia Minor) it is no surprise that the Russians later received it in the 10th century.
In the 9th century however, we can find traces of the three finger sign of the cross (as practiced today by most Orthodox Christians) which of course puts an emphasis on the Holy Trinity. This sign of the cross can be found in the writings of Pope Leo IV of Rome (+855), he wrote: “Sign the chalice and the host, with a right cross and not with circles or with a varying of the fingers, but with two fingers stretched out and the thumb hidden within them, by which the Trinity is symbolised. Take heed to make this sign rightly, for otherwise you can bless nothing”[6]. In the beginning of the 11th c., the Abbot of Eynsham, Aelfric, wrote “With three fingers one must bless himself for the Holy Trinity”[7]. Both these statements are made during a time when the Roman Catholic church was orthodox in their faith. The praise and support for the three-finger sign of the cross continued in the west after the schism with Pope Innocent III (+1216) writing: “The sign of the cross is made with three fingers, because the signing is done together with the invocation of the Trinity”.

The origin of the three fingers sign of the cross can be traced back to the west at least all the way back until 855 when the above mentioned Orthodox Pope Leo IV passed away, which makes it historically certain that this originated before the schism in 1054. This most likely lead to Orthodox people geographically close to Rome to use this three-finger sign of the cross. The Greeks, Serbs, Albanians, Bulgarians and Georgians as well as the Monophysite Copts, Armenians and Syrians all used the three-finger sign of the cross at the time of or closely after the great schism[8]. It is however important to note that the Monophysites crossed themselves from left to right – contrary to Orthodox practice. Today Nestorians in India and Persia also cross themselves with three fingers. In other words, this practice seems to have been the official practice in Orthodox west before the great schism, likewise for the Greeks and their closest Orthodox brothers surrounding them as well as the various above mentioned Monophysite and Nestorian groups. Most likely because of the bigger distance, it did not reach the Russians at the time when it spread from the European mainland. It also important to note that the three-finger sign of the cross has been lost in the west and is today mostly associated with the Orthodox Church – it was “officially” abolished by a papal statement in 1569 in favour of the five-finger sign of the cross symbolising Jesus’ five wounds. The Russians kept the practice given to them in the 10-11th century up until the reforms of the 17th century, which was the two-finger sign of the cross as taught by the likes of Theodoret of Cyrys and St. Peter of Damascus. This is clear as the writing of these two were included in the Russian Typicon of the time.
As we see, the symbolism of the sign of the cross has evolved and been different depending on the local historical contexts. What is however clear, is that the sign of the cross as a concept has always, since the earliest times, been important to Christians and it has contained symbolism as-well as direct expression of dogma. This never was or is simply an empty part of the ritual.
