Doing some research for another project, I came across this from the Holy Father’s trip to Turkey in November 2006, in his Address to the Diplomatic Corps in Ankara:
Turkey has always served as a bridge between East and West, between Asia and Europe, and as a crossroads of cultures and religions. During the last century, she acquired the means to become a great modern State, notably by the choice of a secular regime, with a clear distinction between civil society and religion, each of which was to be autonomous in its proper domain while respecting the sphere of the other. The fact that the majority of the population of this country is Muslim is a significant element in the life of society, which the State cannot fail to take into account, yet the Turkish Constitution recognizes every citizen’s right to freedom of worship and freedom of conscience.
The civil authorities of every democratic country are duty bound to guarantee the effective freedom of all believers and to permit them to organize freely the life of their religious communities. Naturally it is my hope that believers, whichever religious community they belong to, will continue to benefit from these rights, since I am certain that religious liberty is a fundamental expression of human liberty and that the active presence of religions in society is a source of progress and enrichment for all.
This assumes, of course, that religions do not seek to exercise direct political power, as that is not their province, and it also assumes that they utterly refuse to sanction recourse to violence as a legitimate expression of religion.”
That seems pretty clear, doesn’t it?
