Saint Thomas has faith and wisdom when he is willing to die for Jesus; he has reason without faith and without wisdom when he does not understand where Christ is going and he asks for evidence; he is a theologian on the eighth day under the saving burden of the expression – “My Lord and my God”; he is a religious character in general, with more ups and fewer downs. Some want him an ideologist; Thomas is nothing like that, like that are the ones who want him ideologist and attribute him the phrase “believe and do not question”. Thomas has not said something like that, nor did he believe in it. The order, for him as well, is credo – intelligo – credo, and to put faith on a secondary place is pride, as it is indifference to be satisfied only with faith. Faith itself is prepared and... accomplished by the adhesion of intelligence, so that ‘to believe’ is a dialogue between logic and Revelation. Many have faith, but only few also appeal to reason. However, not only Thomas is convinced that in front of the authority of Revelation, reason must obey without seeing itself constrained or defeated. The word of God is true whether reason understands it or not. On the other hand, the Bible is not a scientific book, its purpose is not that of proving the existence of God. Faith suggests, reason requires.
