Lord Jesus Christ, Son of God, You declared with Your most pure lips: “Amen, I say to you, for if two more of you have given counsel on earth concerning all things, - Whatever she asks, it will come from My Father who is in heaven: although there are two or three gathered in My name, there I am in the midst of them.” Thy words are immutable, O Lord, Thy mercy is unconditional and Thy love for mankind has no end. For this reason, we pray to Thee: grant to us, Thy servants (names), who have agreed to ask Thee (the content of the petition), the fulfillment of our petition. But both, not as we want, but as You want. Thy will be done forever. Amen.
A version of the prayer in modern Russian: With deep faith in the immutability of Your words and with hope for Your immeasurable mercy towards us, we humbly ask You to hear Your servants (names) who have agreed to jointly ask You: Lord, let Your Holy will be done. Enlighten us, strengthen us and help us in everything for the benefit of people and for Your glory, Lord. Grant us, Lord God our Savior, to follow You, helping our neighbors to follow the path of salvation, doing works of faith, so that with Your help and by Your mercy our efforts serve to increase good and decrease evil in deeds, words and thoughts. Amen.

Before starting to read a joint prayer, you must take a blessing for this from your confessor (the priest to whom you are confessing).
A magical, occult attitude towards prayer by agreement should be avoided. God cannot be forced to fulfill our desires without His all-good will. God is pleased with the congregational prayer, it speaks of the boldness of its participants (Luke 18:1-8), but let us leave the decision to God, Who, being the Wise and Omniscient, knows better than us what everyone needs first of all for salvation in eternity.
“There are cases when a person believes that he is losing faith in God, but he never had it. For example, one man said that he stopped believing in God after his daughter became very ill, he prayed a lot, but he was unable to save his daughter. In fact, this man did not lose faith in God. He, like many other people, had the view that there is something called "god." This man was sure that if you really ask him for something, you will definitely get it. True Christian faith cannot be lost. When a person truly believes, that is, begins to believe in God, and not only in God, to love Him and strive for Him, then such a person will no longer want to part with this wonderful gift of faith.”
Let us also remember that prayer by agreement is only one of the types of prayer creativity; it cannot replace the main church service of the Divine Liturgy.
