Let's play "Who am I quoting?"

When a thing grows weak and out of date, it is obviously soon going to disappear. That's also true of churches. If a church cannot change, it will eventually die.

Clearly change in both liturgy and structure is inevitable, and this change will probably be radical, if not total. ... the forms the Church assumed in the past inevitably must die.

One is a conservative, one is a liberal. Can you tell who said what?
