JESUS parayed to the father... but he is still GOD because GOD is a triune GOD (father son holy spirit) but there is a hirachy within the GOD head and the father is the greatest so JESUS was praying to the father.
secondly peter attacking the roman soldier was his natural reaction it wasnt commanded by GOD ....like the god of the quran tells muhummad and his followers to do...infact JESUS rebuked peter and told him to put away his sword and gave the teaching of "all who live by the sword die by the sword" and then JESUS healed the mans ear.... there is a big differance between that and muhummad.
peace be with you !
