Таинство вхождения в церковь

Sending the disciples into the world, the Savior said to them: "Go, make disciples of all nations, baptizing them in the name of the Father and the Son and the Holy Spirit..." (Matt. 28:19-20). So, instruction in faith and, following, a certain action - immersion in water, which introduces a person into the church, includes him in the life of Christ, makes him a member of the Kingdom of Heaven. What is this mysterious action, what is the mechanism of communion with Christ?.. What are the rites that accompany the Sacrament of Baptism? what does it mean to renounce the devil; how it is possible to "adopt" God; what is most important in the Christian life. A priest, a graduate of the St. Petersburg Theological Academy, writes about all this.
