**1. Introduction**

Out of many unexpected, ye<sup>t</sup> decisive dimensions of religion's "come back" in the social-political arena over the last decades, both globally and locally, the revisited relation between "the secular" and "the religious", and as a result, "the political" and "the religious" has emerged. Against the tradition of strict separation of both spheres rooted in the Westphalian-Enlightenment tradition, increasingly visible bridging and even overlapping of both domains has been "discovered" or "rediscovered" (Berger 1999; Philpott 2002; Haynes 2007; Thomas 2005). Following Scott Appleby's ambivalence of religion (Appleby 2000), the "both and" approach referring to "religious and secular", substituting the old "either or" approach, has been postulated by many. Vendulka Kubálková proposes the overcoming of dualism and recognition of coexistence of religion and politics through political theology (Kubálková 2000). Marc Gopin speaks of negotiating religious and secular contributions to social change (Gopin 2015). Erin Wilson suggests relational dialogism (Wilson 2012). Slavica Jakeli´c conceptualizes secular–religious encounters as peacebuilding (Jakeli´c 2015).

The idea that the sacred can be part of the secular is one of the Durkheim's most radical and underappreciated claims regarding religion (Barnett 2015). Today, the very categories of the religious and the secular in the public sphere are being revisited, reworked, and rethought (Mendieta and VanAntwerpen 2011). The mentioned reconceptualization does not only refer to some specific areas of common interest in which secular and religious actors have cooperated, but it also applies to mutual recognition of the religious and secular domains as such in domestic and global politics. The expression of this recognition has been the influential concept of post-secularism which, though contested (Mavelli and Petito 2014), opens a new space for mutual appreciation and mutual inspiration (Haynes 2016). In the post-secular society, the liberal ethics of citizenship requires from both religious and secular citizens a "complementary learning process" (Habermas 2005). According to this approach, in the post-secular society, believers and non-believers "have cognitive reasons to take seriously each other's contributions to controversial subjects in the public debate" (Ratzinger and Habermas 2006).

Religious–political cooperation emerged first in such traditional crucial areas of religious and faith-based actors' activities as development and humanitarian aid. Soon, the kind of badly needed "symbiosis" was unveiled in the area of conflict resolution and peacebuilding (Johnston and Sampson 1994). As the concept of "peace" has been gradually reconceptualized and broadened, the religious and secular approaches found common ground stressing the relational and transformative dimensions of conflict resolution and peacebuilding (Galtung 2007; Lederach 1999). As a result, religious "thinking" as well an religious "doing" have to a certain extent been transferred to the domains that had been reserved earlier to political decision-makers and referred to as "high politics" (Seiple and Hoover 2004; Johnston 2003; Surmacz 2013). Contribution of religious and faith-based actors, constituting a crucial share of the civil society sector, has thus increasingly been perceived not only as a type of "first-aid", but also as a premise of reshaping the relationship of power and authority of the state in contemporary global politics (Wilson 2014). Eventually, based on the assertion of the critical role of the religious and faith-based actors in improving the level of comprehension and mutual understanding in an increasingly culturally pluralistic and politically fragmented global setting, the concept of religious engagemen<sup>t</sup> has been proposed (Appleby et al. 2010; Petito and Thomas 2015; Mandaville and Silvestri 2015).

According to the concept of religious engagement, the role of religious and faith-based non-state actors cannot be reduced to charity and humanitarian aid performed in the international arena. Due to their social but also political capacity, they have to be recognized as partners whose potential not only can, but in fact has to be, considered at the political-making level in the area of foreign policy. The essential contribution that religious communities and non-state actors can make is a new form of knowledge, which is generated through the encounter and dialogue with religious communities and religious actors. The approach is based on the assumption that in the contemporary world, knowledge is constructed from the bottom and not from the top, and thus the bottom layers of the society and not the top ones "can also be the preferential place for epistemology, for discovering what knowledge is, how it is constructed and in whose interests it is constructed" (Petito and Thomas 2015) in the area of global politics. As such, religion needs to also be understood as part of historical progress. The result of the emergence of a new secular–religious partnership is the stretching of political imagination and creating new practical innovations to respond to numerous global challenges (Petito and Thomas 2015; Petito 2019).

Although referring to the religious perspective has not (yet) become a universal pattern, it has gradually been included into the wider discourse in the context of growing significance of civil society initiatives and track II diplomacy. Additionally, within the framework of existing church–state relations in some states, religious and faith-based non-state actors have become, to a certain extent, representatives of track I diplomacy (Stensvold and Vik 2018). As Ra ffaele Marchetti rightly stresses, it is thus important not only to realize the increasing influence of the civil society actors on the country's foreign policy, but to also realize how foreign policy is increasingly made in the first person by the civil society actors themselves (Marchetti 2018).

The significance of religious contribution in the normative sense, but also through creating a specific set of proposals to the most challenging problems of the present era, has been well evidenced in the case of migration issues. When analyzing prospects of dealing with the problem of migration a decade ago, it was possible to state that the liberal state may choose to develop a systematic approach to the problem of immigration, which means it can come up with a view of what kind of people it wants to include or exclude, but it may also choose not to develop such an approach (Risse 2008). The second option no longer seems possible, which proves the dynamism of the situation as well the necessity of quick, innovative reaction. In the face of the increasing challenge of migration, some very harsh responses to the problem were applied in countries like the USA or Australia, as well as in some countries of the CEE region. The migrants were either rejected the possibility of entering the country under any conditions or they were, as in the case of the USA and Australia, directed to detention centers that provided heavily criticized standards of treatment. Finally, during Donald Trump's presidency, the procedure of separating the illegal immigrants from their children at the Mexican–American border was performed based on the "zero tolerance" policy (Foulkes 2012; Mittelstadt 2018). Meanwhile, the innovative measures rooted in the civil society initiatives have been introduced, constituting a valuable alternative in terms of ethical and political reaction to the drama of migration. As the examples of Australia and Italy show, religious communities and faith-based actors have always been actively involved in these responses. Using the concepts and practices consistent with faith-based hospitality they were able to challenge public discourse and to propose measures reflecting a wide, human-oriented perspective (Wilson 2011; Bernardo 2019).

In Italy, the project of Humanitarian Corridors introduced in 2015 by the group of civil society actors in agreemen<sup>t</sup> with the Italian governmen<sup>t</sup> resulted in creating new channels of engagemen<sup>t</sup> and effective support for the most vulnerable ones within the existing legal framework. The solutions based on mobilization of the society and creating a big solidarity net have been recognized and appreciated at the governmental, European, and global level as the legal and safe resettlement of the asylum seekers. Although what religious and faith-based bodies have proposed and achieved in this regard cannot be perceived as an "all-encompassing" solution, they did e ffectively utilize their intellectual and material resources to creatively emphasize the ethical obligations of the governmen<sup>t</sup> and the society (Rolando 2018).

The article is divided into three sections. The first one is focused on the theoretical analysis of the religious–political nexus and, more specifically, the concept of "religious engagement", which while referring to the area of foreign policy is also more or less directly a ffecting the domestic political developments in which religious and faith-based actors are engaged. In the second section, the religious and faith-based actors' role is discussed within the wider framework of the civil society sector regarding the evolution of mutual relations between the civil society sector and government. In this part, the issue of the specific placement and understanding of the concept of peace by the religious and faith-based actors is also considered. The third section deals with the problem of dialectics of migration perceived in the context of "duty dilemma" (Delsol 2016) between the political–cultural duty of the governmen<sup>t</sup> to protect its population, territory, and cultural identity, and ethical duty to provide support to those whose lives are endangered.

In this paper, I propose looking at religious engagemen<sup>t</sup> through the prism of two major approaches developed in the religious context, especially Christianity, serving as the basic aim but also the instrument of constructing and reconstructing of the socio-political order, namely the relational and transformative approach. As the ordering remark, it needs to be emphasized that the project of Humanitarian Corridors discussed in the article has been selected due to its growing international visibility and e ffectiveness, as just one among numerous initiatives directed at supporting migrants undertaken by multiple faith-based actors.
