In April 1392 Easton was admitted, with a papal endorsement of the exchange, as rector of Hitcham, Suffolk, in return for which he surrendered the prebend of Yetminster Secunda in Salisbury cathedral to John of Ilkilington.

In it he defended the church's authority against the state, apparently attacking the views of Marsilius of Padua, John of Jandun and William of Occam and by implication, also refuting Wyclif's theology as false and erroneous.

A number of his other works still exist, as do some of the manuscripts of his library, which were shipped back to Norwich from Rome in six barrels, and he composed the Office for the Visitation of Our Lady.

He also laboured for the canonisation of Birgitta of Sweden in 1391 with a structured refutation of a Perugian 'Devil's Advocate', in a document in which he defended women's visionary writings.

Alfonso became director to Catherine of Siena, whose confessor and executor was William Flete, the Cambridge-educated Augustinian Hermit of Lecceto, and to Chiara Gambacorta.

Easton's Defense of St Birgitta echoes Alfonso of Jaen's Epistola Solitarii, and William Flete's Remedies against Temptations, all of which appear in Julian's text.
