For to change the Lord's mission from being His death, and that event from actually taking place, and remove the multitudes of attestations to Him being the Son of God would alone require an almost complete rewriting of the NT and very substantial changed to the Old.
And if the Catholic church did so then why did they do such a poor job, as it would not be hard in that case to also add just prayer to an angel or saint in Heaven, and or a reminded to submit to the holy Father in Rome, or one clear example of an infant being baptized, or a NT minister being distinctively called a priest, and changing bread and wine into flesh and blood as a sacrifice for sin and to be consumed in order to obtain eternal life.
Instead of the alleged corruptions taking place, there is not one single manuscript among the thousands we have that supports the Qur'anic contradictions.
And as seen here , the murderer Muhammad damnably radically contradicts the Scriptures, to his eternal horror. Please do not join him!!!
Infant baptism does not seem to belong in the same category as the other things mentioned in the same sentence. There are born-again believers who do not view the issue the same way or from the same perspective. I happen to believe there are sufficient Scriptural evidences for the Covenantal view to warrant the practice and while those evidences may not be as directly stated as you would prefer them to be, that issue still pales in insignificance to the other beliefs and practices listed.
Just my two cents.
Cordially,
