The birth of a Christian family (weddings) takes place with the blessing of the Church, which unites two into a single whole in the Sacrament of Marriage (love). There is a special providence of God about such a family, after which it is based on the evangelical commandment about love.
Marriage is a Sacrament in which, with a free promise to the bride and groom of their mutual marital fidelity before the priest and the Church, their marital union is blessed, in the image of the spiritual union of Christ with the Church, and they are asked for the grace of pure unanimity for the blessed birth and Christian upbringing of children.
This is a sacred custom established by God, in which the grace of the Holy Spirit, which sanctifies and exalts the natural marriage union, is given to the bride and groom, who voluntarily and without coercion enter the paths of married life
