Not my language for sure, and I am SURE that is not on the USCCB list of approved translations!,
I’ve always considered Protestants brothers in Christ. I still do.
The typical Catholics we debate here will hardly affirm their own pope as a brother in Christ (not that he is, but neither were the others. You can see some on the development here . ).
The main thing is that you comer to God with a contrite repentant heart, and cast all your faith/dependence upon the risen Divine Son of God, the Lord Jesus, to save you are a Hell-bound sinner by His sinless shed blood, and thus be baptized and follow Him. But as enlightened by Scripture, the latter will mean leaving Catholicism for conservative evangelical faith.
No, you see, I’ve done that, so while I may be afoul of what you consider the Catholic Church’s version of what my salvation may require, I’ve done nothing less than you have. Nothing I’ve done as a Catholic negates my acceptance of Jesus as my savior, no matter how much you wish it does.
