Fides quaerens intellectum (faith seeking understanding) is almost literally a millennium old at this point https://en.wikipedia.org/wiki/Fides_quaerens_intellectum (and much older if you take it back to Saint John's response to the resurrection John 20:8-9)
And to add another famous example: Galileo Galilei 500 years ago was persecuted by the Christian Church because he (Galileo) defended helio-centrism. [0]

Sorry pal, but Christian Church is firmly in the "believe and do not doubt" camp.
What you wrote is quite obscure.
Much more popular is "believe and do not doubt".
Also: Jesus' response to Apostle Thomas after his resurrection from the dead is recited during every Easter mass: "Because you have seen me, you have believed; blessed are those who have not seen and yet have believed."
