It depends on what sort of "Christian" church you're going to. A TRUE Chrisitan church or preacher will have no problems with this, since Jesus broke all of the old laws about not letting people of different nationalities/ races gather in one place while he was preaching. He was really one of the first people to preach both racial/ national equal rights, as well as to stand up for women's rights (and these views quite likely were why the Jewish church of that time despised him so).
Unfortunately, there are some so-called "Christian" churches that still adhere to Old Testament rules that neither Moses nor Jesus would have supported. This is why the church spent so much time trying to get Jesus to say the wrong thing, since so many so-called scholars misinterpreted Moses' rules and actions before Jesus was born. (Like Moses allowed divorce, but it was permitted for some pretty petty BS by the time Jesus was born).
Now, one of the biggest reasons that segregation was promoted in the US for so long was because white churches felt it was "God's rule" to keep the races separate. (I think it was called "misegeny", the crime of two separate races getting together.) The movie, "Mr. & Mrs Loving" was based on the first interracial marriage that went public in the US, and it shows the horrible way in which these people were treated, in every aspect of their lives.
However, based of Jesus' own actions, neither race nor sex nor nationality come before the importance of spiritual communion. He preached to people of various races and nationalities, and allowed these people to gathert together in a single place (even under a single roof, which was specifically forbidden in his time). Therefore, many of the old rules of the Old testament were completely thrown out by Jesus... to include ignorant adherence to racial separatism.
