clearly in the clear practice of ecumenism you can twist doctrine, obfuscate it, omit it; confuse it; downplay it, pretend it doesn't matter and ignore it.
Another manner in which false ecumenism presents itself is in the denial or minimizing of true Catholic doctrine in dialogue with other Christians.The manner and order in which Catholic belief is expressed should in no way become an obstacle to dialogue with our brethren. It is, of course, essential that the doctrine be clearly presented in its entirety. Nothing is so foreign to the spirit of ecumenism as a false irenicism which harms the purity of Catholic doctrine and obscures its genuine and certain meaning. At the same time, Catholic belief must be explained more profoundly and precisely, in such a way and in such terms that our separated brethren can also really understand it.It is false ecumenism to withhold or disguise true Catholic doctrine in order to attempt to achieve unity when it in fact is not achieved. False ecumenism in practice leads to the indifferentism and modernism. The blending of all Christians without reference to doctrine, known at times as “pan-Christians,” is false ecumenism that was condemned by Pope Pius XI and is incompatible with the Second Vatican Council’s Decree on Ecumenism.
From the OP.
The author should be telling this to the cardinals bishops and priests.
