Never said we should discard the crucifix. We need to be careful when we speak of innovations, too. At one time, placing the image of Christ on a three-dimensional cross was novel. It caught on. People found and still find it meaningful to venerate or reverence a crucifix.
Some churches use a cross for processions, but retain a crucifix as a devotional image.
Your pastor has a novel idea of theology as well. Helpful for him, perhaps, but misleading if raised to the status of dogma. I also find his abrogation of the Sign of Peace interesting. Apparently, some pastors take discretion that doesn't belong to them in changing the liturgy so. The fact that a rite includes items added or restored in 1969 makes it no less valid or prayerful or meaningful than a rite promulgated in 1570.
