Liturgy the first topic of discussion

On 15 October 1962, the Council of Presidents decided that the first topic of discussion at the Council would be the schema on the liturgy, De sacra liturgia.

This was thought likely to be among the least controversial subjects as well as being the best schema of the seven that were distributed prior to the Council.

Cardinals Liénart and Frings along with Tisserant, Ruffini and Alfrink voted in favour of this.
