Canon 31 of the Stoglav Council reads as follows: "The sign of the cross must be made according to the rules, in the form of a cross; and the right hand, that is, the dextral hand, must be used in crossing oneself, with the thumb and the two lower fingers joined together, and the extended index finger joined to the middle finger, slightly bent; thus should prelates [and] priests give their blessing and thus should men cross themselves… It befits all Orthodox Christians to hold their hand thus, and to make the sign of the cross upon their face with two fingers, and to bow, as we said before. If anyone should fail to give his blessing with two fingers, as Christ did, or should fail to make the sign of the cross with two fingers, may he be accursed…"

In 1589, Ecumenical Patriarch Jeremias II Tranus visited Russia and elevated the Metropolitan of Moscow to the rank of Patriarch. The Greek and Russian Churches thus maintained their unity without fail, despite the fact that the Greeks made the sign of the cross with three fingers, while the Russians made it with two.
