To love your brother is a part of the message of the gospel. Only some weird sense or distortion can eliminate that message.
Can I ask you what you have faith in?
Christ.
It can not be faith in Christ as your savior
Ahh, resorting to making it personal. Iscool - note that it isn't the Catholic Church involved in this judgment of the heart. Can we count on you quickly flogging this individual with your chastisement about judging people?
Is it faith that your works will be sufficient?
As we've said many times, and as stated in Scripture, it is not works alone. Nor is it faith alone. It is not either/or.
faith that obeying the laws of the church and receiving the sacraments will save you?
Faith in Christ and loving your brother.
But missing mass is a mortal sin and sends a Catholic to hell if not confessed in a confessional ...seems to me that is faith in the church
BTW who is your brother?
