The Governing body and the Apostles in the first century were also infallible!! Never the less they would not tolerate such talk! Also in line with your comments about Jesus. Paul to was accused of Apostasy by the religious leaders against the mosaic law!
As we know in the Christian Greek Scriptures Apostasy is used primarily with regard to religious defection; a withdrawal or abandonment of the true cause, worship, and service of God, and hence an abandonment of what one has previously professed and a total desertion of principles or faith!! If you can condone such behaviour and justify such comments then you also need to rethink where you are heading or are at!!
Remember, it is evident that there is a distinction between a ‘falling’ due to weakness and the ‘falling away’ that constitutes apostasy. The latter implies a definite and willful withdrawal from the path of righteousness. Whatever its apparent basis, whether intellectual, moral, or spiritual, it constitutes a rebellion against God and a rejection of his Word of truth!!
