Among the eighteen Mahapuranas, perhaps the most popular one among Vaishnavas today is the Bhagavata Purana, AKA the Srimad Bhagavatam. Yet Ramanujacharya, the most prominent member of the Sri Vaishnava sect (of which I'm a member) doesn't quote from it at all in his writings.
Various explanations of this have been proposed, e.g. that the Bhagavatam was viewed as having Advaita overtones until the time of Madhvacharya, or that the Bhagavatam was a devotional text and thus not suited for Ramunjacharya's philosophical arguments with his opponents. Still, a lot of Western Indologists use this fact to argue that the Srimad Bhagavatam was a later work composed after the time of Ramanujacharya, and that all the passages in Hindu scripture (e.g. in other Puranas and the Mahabharata) which refer to the Bhagavatam are later interpolations.
But my purpose here isn't to adjudicate this dispute, other then to say that as a Sri Vaishnava I personally accept the Srimad Bhagavatam as an authentic work composed by Vyasa. My question is, who was the first Sri Vaishnava Acharya who actually quoted from the Srimad Bhagavatam in his works?
Note that I'm not looking for allusions to stories that happen to be in the Srimad Bhagavatam. I'm looking for direct quotes from the text of the Bhagavatam. And I'm specifically interested in Sri Vaishnava Acharyas, since the Bhagavatam now plays such a prominent role in the Sri Vaishnava sect.
