The ruling on the statement that the Christians are not disbelievers

Question:
Honorable Shaykh, may Allah grant you success. In our country, Sudan, there is a man known as the Islamic thinker who says that the Christians are not disbelievers, and that the saying of Allah the Exalted, "Indeed, they have disbelieved," means "they covered up." He also advocates for the convergence of religions. So, do we call what the Christians are upon today a religion, even though they deny the descent of Jesus at the end of time?

Answer:
A religion is called a religion, even polytheism is called a religion. Allah (Exalted and Majestic is He) said: up to His saying, "For you is your religion and for me is my religion." So a religion is whatever a person professes, whether it is true or false. It is called a religion, but it is a false religion. As for the claim that there is no difference between Muslims and disbelievers and that they are all Muslims, whoever holds this belief is a disbeliever. Whoever holds this belief is a disbeliever; because he equated disbelief with faith, and did not distinguish between them, and did not disavow the disbelievers. So this is considered disbelief.
