Are all blasphemous thoughts that enter our mind sinful?
No.
(I will re-post a post I posted before - general remarks about “unwanted thoughts”)
UNWANTED THOUGHTS
All sorts of thoughts can happen to us out of the blue…(not sought etc)
The fact that a Blasphemous thought happened to one- does not mean per se there was *any sin.
*
And for mortal sin one needs not only grave matter, full knowledge and deliberate *(complete) *consent…
Just cause a thought happened to you does not mean there was
any sin. Let alone mortal sin.
Just calmly turn to something good…
Even if the thoughts return and return…or are intensely happening that does not mean there was any sin per se.
The fact that one is does not want them that they are go against what you want can rather be a sign one is well does not want them (does not consent fully). Talk with your Priest in confession about this …get some personal guidance.
Now…
For the next few moments --try real hard NOT to think of an Apple.
then scroll down.
What did you think of?
An apple.
Even though your will was against it (you did not want to think of an apple!)
Now back to unwanted thoughts…
The more you fear and try hard not to have them…the more they will likely come and bother you.
The best thing to do with such thoughts is not to fight them directly --not fear that they will come—simply do not consent and simply and *calmly *turn to something else…(or it may be best to keep doing the good thing one is doing…like they come out of the blue when your at work …keep working…keep praying …etc…calmly ignoring them…turning to something good…)
Ignore such unwanted thoughts like one would ignore a hissing goose or a barking dog. One does not stop to argue with a hissing goose or a barking dog does one? No. One keeps on walking…
(image there comes from a Carthusian Monk from centuries ago…)
Ignore such unwanted thoughts and do not fear them…just calmly turn to something good.
(And if this is more of an OCD matter which- I have heard CA staff mention
catholictherapists.com/ as a resource)
And as others have noted - seek out a Priest as a regular confessor to assist you.
