✔ Concerns about theological syncretism and religious pluralism
The WEA has stirred controversy by former General Secretary Thomas Schumacher's statement that there are no theological differences between the WEA and the WCC. This has raised concerns that it could undermine biblical truth.

✔ Lack of Justification and Benefits
Some criticize that holding the WEA Seoul General Assembly has neither justification nor benefit and could rather lead to division in the Korean church. Some pastors are criticized for taking the lead in hosting the General Assembly, which is an act that undermines the authority and order of the denomination. It is pointed out that the justification for hosting the General Assembly is lacking and the tangible benefits that can be gained from it are unclear.
