No the Corinthians were spiritual having the Spirit in them 1 Cor 6:19
19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
They had been given the Spirit to know the things of God 1 Cor 2:12-13
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things[Salvation things] that are freely given to us of God.
13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
