Black US Protestants are becoming more comfortable with marriage equality.
A survey by the Pew Research Center shows that, when compared to last year, more and more mainline Christians approve of gay marriage.
The most significant difference is with black Protestants.
'The sharpest change has occurred among black Protestants, only 32% of whom favored same-sex marriage in our aggregated 2013 polling,' Pew Research notes.
'A survey we conducted last month found that figure has now risen to 43%,' the organization continues.
The study also points to an uptick 'among white mainline Protestants (from 55% in 2013 to 62% this year).'
White evangelical Protestants remain the most opposed to same-sex marriage. Last year only 23% of that group stood for gay marriage. The number has not changed.
