I think a more complete answer would be to say that:
Faith as defined in my earlier post, can be a vice OR a virtue in #1 depending on who the trust is put upon and quality of evidence used.
Example: Faith #1 aka "trust" in many new people on little/no evidence can more readily be a vice than faith in your best friend you have known a long time and have demonstrated evidence for trusting in them for something (which can more readily be a virtue)
Faith as defined in my earlier post can be a vice OR a virtue in #2 depending on which doctrines are believed and how closely they follow or support adherance to universally accepted morals (ie no murder/rape/etc)
Example: Faith #2 aka "belief" in a God or scripture that tells you to kill those who don't believe what you do can more readily be a vice than belief in a God or scripture that tells you to love everyone including your enemies and provide for the sick/poor (which can more readily be a virtue).
Thus Faith in both definitions can be a vice or a virtue dependent upon where it is placed and to what degree one acts upon it.
