One cannot be saved and hold to Roman Catholic heretical doctrines.
If heretics cannot be saved, then there I go. On the last day, we will all have some bit of heresy to repent of.
Yes but not an image of Christ created in your mind, that would also be idolatry, only the image of Christ given to us in scriptures, which is contrary to comtemplative meditation
How so? To me, meditating on some bit of Scripture seems very contemplative. Dietrich Bonhoeffer used to give his students a verse of Scripture and ask them to spend thirty minutes each day meditating on it. If that's not a contemplative practice, I don't know what is.
