As a man I can honestly say that were I to be pulled into staring at those images I would in all likelihood commit a sin if not necessarily by direct thought and even possible subsequent action then at the very least by having willfully and knowingly placed myself in the immediate occasion of sin.
The images are just pictures of what you will see in your SSPX chapel every Sunday, so if they are so dangerous to you as you describe, why don't you take the same holy anger you exhibit here and apply it to the real world in your chapel? The first place to apply it is where you are in charge, your family. Marilyn Monroe in those pictures is a pretty young girl like 23, maybe an older less attractive woman wearing the same thing does not affect you the same way? Don't attack the messenger, go and take care of the matter in the real world.
The OP is no small irony in so much as it displays 2 impure fashion images and then complains about impure fashions. Unfortunately, there are some Catholic websites such as traditioninaction.org that seem to think it is perfectly all right to place very impure images on their sites. (It is particularly ironic for tradtioninaction.org to do so in so far as they carry a number of excellent articles rightly decrying the use of immodest/impure fashions.)
Instead of applying Traditioninaction's excellent information and articles,
I hope you are not just attack the messenger and doing nothing in the real world to take care of the matter.As Catholics we should never forget the basic Catholic principle that one may never do evil in order to bring about good. That includes the placement of impure images on the Internet -- especially on a Catholic site!
That is correct, except, what are you doing about the impurely dressed real people all around you in your chapel?
If those pictures are as impure as you state why not declare it from the rooftops at your chapel?
