Germany had re-invented itself rather than dealing with what had taken place. A meeting with Emanuel Hirsch, which was only granted when Frei agreed not to raise the question of Nazism, confirmed Frei's impressions. Frei also spent time in England, which he appears to have enjoyed, and even though he found that nothing much was going on theologically in Cambridge that interested him, he frequently referred back in later life to how much he had enjoyed his time there. Earlier theological work Frei was appointed Associate Professor in 1963. Then, between 1966 and 1968, almost as an interruption to the work which was proceeding towards Eclipse, Frei produced a 'theological proposal' – a lengthy article, expanded a little later into an adult education course, commented on in a lecture, and accompanied by a contribution to a seminar on the work of Karl Barth, after the latter's death. This 'proposal' emerged to wider scrutiny only some years later, when (in 1975) the adult education course was republished as The Identity of Jesus Christ. This strange project, an exercise in the rethinking of the structure and bases of Christology and, even though Frei soon developed doubts about various important aspects of it, it sets the tone and the themes for most of the rest of what he went on to say in theology. After that brief flurry of activity, Frei returned to honing his work on Eclipse, which was eventually published (to much wider recognition) in 1974. By that time, Frei had been Acting Master of Silliman College, Yale (1970–1971), and Master of Ezra Stiles College (from 1972), the latter a post he was to hold until 1980. The publication of Eclipse coincided with Frei's appointment to a full Professorship. Frei then entered another period of comparative silence, although this time it was not in complete obscurity: his name was out, rattling around in theological and historical circles attached to the massive and ground-breaking Eclipse, with Identity as a strange accompaniment. His silence was not so much due to the pressures of teaching or to isolated and exhaustive research, but to his commitment to his job as Master of Ezra Stiles. Frei also served as chair of the council of masters in 1975. The 1970s were a difficult decade for Frei. He found himself troubled about his links to the church. Firmly convinced theologically that he should have some kind of ecclesiastical
