Cleveland (AP) -- An unprecedented gathering of Ohio Roman Catholic priests this week will focus on an institution of marriage that the church believes is under attack.

Dan Andriacco, a spokesman for the Archdiocese of Cincinnati, says the meeting Thursday and Friday in Columbus will address increases in divorce rates and people living out of wedlock, as well as the growth of same-sex unions.

The state's bishops and nearly 700 priests are expected to attend.

Church officials believe it will be Ohio's first-ever statewide gathering of priests.

Clergy members will listen to speakers and hold discussions, the results of which will be sent on to the U.S. Catholic Conference of Bishops.

It's working on a pastoral letter on marriage and family life.
