Earlier quoted context omitted.
I'm not familiar with Kriss or Tao Lin, but First Things, while predominantly Catholic, is ecumenical. They have regular columns from protestants, Jews, Muslims, and even Peter Thiel. I've found they will print some authors from outside their normal milieu if they offer some insight that would benefit the high brow literary conservatism that characterizes the magazine.
"First Things, while predominantly Catholic, is ecumenical. They have regular columns from protestants, Jews, Muslims" For what it's worth, "ecumenical" means promoting Christian unity. So if Catholics carry dialogue with protestants, it may be ecumenical in nature, but with Jews or Muslims (as commendable and fruitful as it may be, but that's not the point) it can't be called that.
Maybe it's specific to american english.
I checked cambridge dictionary and it confirms that definition : tending to support and encourage unity among different religions
Merriam-webster has a similar definition : Worldwide or general in extent, influence, or application
Also collins dictionary : interreligious or interdenominational
