Pope Francis's has described his vision for a synodal Church, not simply as a once off programme of renewal, but as God's desire for the Church of the third millennium. As such, it aims to concretise the ecclesiology of the Second Vatican Council, making the Church today more manifestly one of communion, participation, and mission. It differs from previous synods and Councils in history in that it more directly invites and involves all the baptised in a direct process of listening and discernment to the voice of the Holy Spirit. This paper aims to understand from a theological perspective how listening will work in a synodal Church, by exploring firstly what we mean by the ecclesiology of communion from the Council. Such an ecclesiology, manifesting the equal dignity of the faithful in Christ, will ground listening at the level of participation in God as well as acknowledging the gift of infallibility given to the whole Church. It means calling on the Holy Spirit to help discern how and where, the apostolic deposit of faith has been received by members of the body. It also explores what we mean by listening to the sensus fidei of the whole body and how the authority of laity and hierarchy operate both in united but distinct ways within a synodal process grounded in communion ecclesiology. Overall, such listening is to be done carefully for the sake of the Church's mission as the sacrament of salvation to the world.

The study of suicide is an emerging and important interdisciplinary field in central and east European Studies. The importance of the topic is self-evident. Suicide is literally a matter of life and death, important in its own right; but the study of suicide is also a means of addressing larger questions in the history, culture, and politics of the region. Suicide is almost always an object of grave concern whenever and wherever it occurs, thus prompting a wealth of statistical and discursive documentation and information. It is a supremely individual act—arguably the supreme individual act—but also one that implicates and involves the community or society in which it occurs. This is especially true during times of seeming or actual spikes in the occurrence of self-killing, so-called “suicide epidemics” that demand immediate attention and explanation. But the reasons for suicide are also often highly elusive, creating what Irina Paperno has termed a “black hole” into which is drawn the explanations, rationalizations, and justifications of all those proximate to the act. In this way, to study suicide in its social context is also to study the attitudes and the anxieties of the society in question. It is to look through a glass darkly: to see a reflection of contemporary concerns and attitudes that might otherwise have gone unseen.

We establish some properties of $\tau$-exceptional sequences for finite-dimensional algebras. In an earlier paper, we established a bijection between the set of ordered support $\tau$-tilting modules and the set of complete signed $\tau$-exceptional sequences. We describe the action of the symmetric group on the latter induced by its natural action on the former. Similarly, we describe the effect on a $\tau$-exceptional sequence obtained by mutating the corresponding ordered support $\tau$-tilting module via a construction of Adachi-Iyama-Reiten.
