New sectarian fault lines drawn in Egypt

Don't get this logic from the Brotherhood:

The Salafist Front asked President Morsi to consult with Muslim scholars before attending the Easter mass, and banned its own officials from acknowledging the Coptic Easter holiday. Muslim Brotherhood Guidance Office member Mufti Abdel Raham al-Barr, who is also a professor in the Al-Azhar University, said that congratulating the Copts on the Orthodox Easter is “religious haram [taboo],” adding in a statement that “it is illegitimate to offer greetings for something that blatantly contradicts our creed….Our creed, as Muslims, is unequivocal: Christ – peace be upon him – was neither killed nor crucified, as Allah protected him from the Jews and elevated him to His presence. [Prophet] Isa – peace be upon him – was not crucified to be resurrected. Accordingly, there is no need to congratulate someone on something we know to be a falsehood, even though we do not deny our partners in the nation the right to believe or act as they please.”  
Al-Barr, who is an influential Muslim Brotherhood member, went on to distinguish between offering acknowledgment of other Christian holidays (like Christmas) and doing so for Easter: “Congratulating our Christian partners in the nation on their various occasions and holidays is an expression of charity ordered by Allah and of righteousness from which He has not banned us as long as it is not at the expense of our religion, and does not pronounce… any religious slogans or expressions that contravene the principles of Islam, and does not constitute any admission or acceptation of their religion or participation in their prayers. Rather, these would merely be words of courtesy common among people and would not entail any religious contraventions. There is nothing wrong, in my opinion, in greeting [Copts] on Christmas, as we believe that Isa – peace be upon him – is one of the primary prophets, that he is human and that his birth was one of Allah’s miracles.”

Surely if you can greet them at Christmas, which celebrates the birth of the son of God (in Islam Jesus is a simple mortal prophet), you can also greet them at Easter. The lack of logic in the differentiation between the two suggests that al-Barr is either doctrinally a Salafi or that he does no want to offend Salafis. Like President Morsi's decision not to attend the mass, it is a striking lack of understanding of the symbolic value of having even an Islamist president pay respects to the church and the Christian community, which can only be explained by intolerance.
