"Second, we also got a more authentic liturgy of the people of God, in the vernacular language"

This quote by Hans Kung is referring to the Second Vatican Council, which was a conference of the Roman Catholic Church in the 1960s. The Council was a significant event in the history of the Church, as it brought about a variety of modifications to the liturgy and other elements of the Church. In particular, the Council enabled using the vernacular language in the liturgy, which was a significant shift from the standard Latin. This indicated that the liturgy was more accessible to the people of God, as they might understand it in their own language. This was a major advance in regards to making the Church more available and inclusive, and it was a major part of the reforms caused by the Second Vatican Council.
