Infants cannot consciously proceed to the Sacrament of Baptism, therefore the baptism of children is performed according to the faith of parents and godparents, who become full participants in this Sacrament along with the infants.
Only baptized people of the Orthodox faith, who have not fallen from church communion, are allowed to the sacraments of the Church. Departure from the Church occurs not only as a result of committing grave (mortal) sins, but also in those cases when people did not proceed to the Sacraments of Holy Communion and Repentance for a long time. If one didn't take communion — in fact, one didn't want to have parts with God. Jesus said unto them:" Verily, verily, I say unto you, unless you eat the flesh of the Son of Man and drink his blood, you will not have life in you. He who eats My Flesh and drinks My Blood has eternal life, and I will raise him up on the last day "(John 6, 53-54). Therefore, before participating in the Sacrament of Baptism, those who fell away from church fellowship must be reunited with the Church through repentance. In the Sacrament of Confession, a person receives forgiveness for his sins and is reunited with the Church.
These preparatory requirements apply not only to the parents of the child (in extreme cases, to one of them), but also to the godparents. In addition, those who approach the Sacraments of the Church must undoubtedly know the basics of the Orthodox faith. Therefore, at a minimum, it is necessary to understand well the interpretation of the Creed.
Baptism of infants without parental training is permissible only " for the sake of the mortal fear ", i.e. in case of a threat to the life of the child (serious illness, urgent complex operation).
If you live a full-fledged church life and embarked on the Sacrament of the Holy Communion no later than a year prior to Baptism, then immediately before the baptism of a baby, it is not necessary to confess and receive communion.
If a baby is baptized, then they must have godparents, whose duties include the Christian education of their godchildren. They will be held for them accountable at the judgment of God.
To give the child a Christian upbringing, the godparents themselves must live a Christian life, pray for their godson or goddaughter.
