Answer 2

Vatican II did not change doctrines/dogmas because they don't change. What were changed were some practices.

Within the Church there are two main types of law: Divine (God's) law, and Church law. Divine law is those revealed truths which God has entrusted to His Church for safekeeping and instruction of the faithful. Examples of Divine law are the 10 Commandments and the Church dogmas (there is one God, there are 3 persons in the one God, there are 2 natures in the one person of God the Son, grace is a gift of God, Jesus founded the Church in order to continue His work of redemption for all time, abortion is murder, etc.). Divine law cannot be changed by the Church or anyone else as it is God's revealed truth.

Church law constitutes those earthly rules and regulations which the Church has found necessary to enact to ensure that the great commission given to the Church by Christ is fulfilled: "Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you." (Matthew 28:19-20, NIV).

The ability to make these rules was given to the Church by Jesus Himself and is referred to as "the ability to bind and loose." Church law covers a large variety of rules for the Universal Church (the Code of Canon Law, of which there are 1752 canons, for example) as well as rules unique to a particular region or diocese.

Examples of Church law would be whether priests may marry, how long a fast is to be observed before receiving Holy Communion, and what training and instruction is required to be recognized as an extraordinary minister of the Eucharist. Church laws can be changed by the authority which enacted them.
