In more recent years I have been terribly offended and hurt by announcements in the church missal or from the pulpit that those who aren't Catholics cannot receive Communion, even when they believe almost the same things that we believe, even when they are Christians and people who live out the spirit of the Gospel. I have certain people in mind when I say this, people I work with in a church soup kitchen for the homeless--but I won't mention their names here. But in my mind, the Catholic church sins against the wishes of Jesus and the spirit of Christianity when it excludes my friends from Communion.
There are so many other examples of the Church sinning against unity/oneness/universality and not adhering to the guiding principle of "What would Jesus do?" I think especially of the discrimination against gay people, divorced people, and even former priests. A good friend of mine, a former priest of the Diocese of Erie, was excluded from Communion because he was not "laicized"--and he was not laicized because the Church put a hold on laicizing former priests, thinking (I imagine) that it would keep more priests from leaving. Ha ha!
So many sins of the church that I love! I want a welcoming Church!
