Did Buddha say there was Amida Buddha and a Pure Land?
Yes, it is in the Sukha-vativuha Sutra also known as the Larger Sutra on Mitayus. If you do a Google search, you will probably come up with the BDK translation. In this Sutra, Sakyamuni Buddha explained how Dharmakara Bodhisattva made 48 Vows, and upon fulfillment of these vows became Amida Buddha (the combination of Amitayus and Amitabha).
